One well-known tape preservation method is baking tapes, which is (almost) exactly what it sounds like. Here’s an overview of how it works.

What Is “Baking” An Analog Tape? 

As magnetic recording tapes age, the binder used to adhere the magnetic material to the backing can become unstable, forming a sticky residue. This deterioration, known as sticky shed syndrome, can damage both the tape and the playback equipment. 

Datarecovery.com’s technicians can address “sticky shed” syndrome and other physical issues that affect analog video cassettes in storage.

“Baking” is a process used to repair sticky shed syndrome and restore audio recordings stored on magnetic tape. In professional video restoration laboratories, the process is performed with specialized equipment that maintains appropriate heat and humidity conditions (despite the name, tapes shouldn’t be “baked” in a conventional oven— most oven thermometers aren’t especially well-calibrated, and a difference of several degrees can cause warping).

The tape is heated to 130-140°F for up to 48 hours to remove any moisture trapped between the layers of tape material. The temperature and bake time can vary based on the width of the tape and other factors. 

The baking process ensures that the physical shape of the binder remains intact and prevents further damage from occurring while it is being played back. As a result, sound quality is improved and distortion is reduced. 

However, baking is not always an appropriate option. Without strict controls, baking can damage the tape binder, permanently destroying audio or video.

When Video Cassette Baking is an Option for Media Restoration

The best practice is to evaluate each cartridge individually. If the symptoms of sticky shed syndrome are present, technicians must also ensure that high temperatures will not compromise the tape’s mechanical integrity. 

In some cases, video/audio quality may be restored with techniques that carry a lower level of risk (such as cleaning the tape with appropriate chemicals or respooling the cartridge). These methods must be performed alongside the bake for optimal results. Tape decks must also be inspected and repaired regularly to ensure the best possible outcomes. 

At Datarecovery.com, we use non-destructive methods. While we occasionally use environment-specific restoration techniques (the more-technical term for heating tapes), in our experience, other methods are more effective in the vast majority of cases. 

We may consider environmental restoration techniques if a tape shows specific signs of oxidation:

• The sound quality of the audio has degraded significantly.
• The audio track is out-of-sync with the video.
• The tape creates a squealing sound when passing the playback head.
• The surface of the tape has a gummy, flaking residue.

How Does Video Baking Work?

During the baking process, the video cassette is placed in an enclosed receptacle with heat and humidity controls. The temperature is increased slowly and maintained . 

During this time, any moisture trapped between the layers of plastic will evaporate and any distortion present on the recording will be reversed due to its re-solidification into its original shape. 

Some tapes may be baked multiple times — but again, the process carries a degree of risk. And if the tape is not properly cleaned, respooled, and played back with appropriate equipment, the results of the restoration may suffer.

In other words, baking an analog tape is a delicate process that requires specialized equipment and expertise. At Datrecovery.com, we’re able to choose the appropriate restoration options for ¾-inch U-matic, Betacam, and dozens of other formats — and provide the best possible digitization solutions at scale.

That project was largely successful, but it highlights the importance of proper video cassette storage. While we have developed proprietary techniques to obtain the best possible signal quality, digitization is limited by the quality of the analog media. When U-matic tapes lose visual or audio information, that information may be gone forever. 

With that in mind, let’s discuss why digitization is crucial — and how storage conditions can impact the quality of an analog video archive.

1. Over time, U-matic tape binders break down. 

¾-inch tapes aren’t especially complex. They contain a binder, an adhesive with polyurethane that holds oxide atoms to the tape. 

The oxide atoms represent the video and audio signal. The binder also contains lubricants that allow the tape to pass smoothly over the heads that read the video/audio information. 

Eventually, the binder undergoes a chemical change that results in the urethane rising to the top of the surface of the tape. This is called sticky-shed syndrome, for reasons that are obvious if you’ve ever dealt with an older tape: 

• The tape sticks to the reels of the deck, often creating an unpleasant sound. 
• Playing the tape will leave visible material on the heads of the tape deck.
• During playback, the video may distort and the audio may fall out of alignment.
• As degradation progresses, large portions of video/audio may become totally unreadable.

This issue can be partially reversed by “baking” the tapes — storing the tapes for a short period of time in a high-temperature environment with controlled humidity. This doesn’t mean that U-matic tapes can be treated in an oven. “Baking” is a technical process, and the quality of the “bake” will directly affect the health of the tape. 

After baking, a U-matic tape will continue breaking down. It’s important to digitize tapes with sticky-shed syndrome as soon as possible — and to get the highest quality transfer possible, since the tape may be unusable in the future.

2. Excessive humidity can contribute to sticky-shed syndrome

Since hydrolysis occurs due to water absorption, it’s important to store U-matic tapes (and other analog and digital video cassettes) in a cool, dry space. 

Unfortunately, proper storage does not completely prevent tape degradation. Ambient air has a certain amount of humidity, and U-matic binders will eventually absorb some water; hydrolysis is effectively unavoidable, even under precise storage conditions.

With appropriate storage, a U-matic tape can retain its signal quality for 20 years. The tape is still readable after this point, but some amount of signal degradation will occur. 

In addition to binder deterioration, other issues can cause tape degradation:

• If tapes were in regular use, the control track playback and tracking can suffer due to mechanical wear.
• Tension control issues can cause slippage, which can cinch the tape during playback.
• Layers of tape can stick together. This is called blocking, and may occur due to high heat.

U-matic ¾-inch tapes should be inspected and treated prior to digitization. Playing a degraded tape can cause irreversible physical damage.

3. U-matic tape decks also degrade over time.

Sony no longer produces U-matic tape decks, and like all mechanical devices, video playback equipment becomes less reliable over time. Even if your organization has a library of U-matic decks, you’ll need to inspect your equipment thoroughly before attempting digitization on your own — head clogs and other issues can damage the source media. 

At Datarecovery.com, we’ve developed specialized processes for U-matic digitization. Each tape is thoroughly inspected, cleaned, and coated with lubricant prior to playback. When necessary, we can treat tapes with sticky-shed syndrome in controlled environments, using non-destructive techniques to preserve signal quality.

Greg Crutcher has had a storied career, serving as producer or director on six cable network series and nine specials. His credits include directing CMT Showcase for Country Music Television (CMT), Billy Ray Cyrus: I Give My Heart to You for TNN, and more than 100 music videos for legendary musicians such as Garth Brooks, Travis Tritt, and Steven Curtis Chapman. 

Much of Crutcher’s work can be found on YouTube — but not all of it. In late 2022, Crutcher set out to digitize eight Sony U-Matic ¾-inch tapes from the beginning of his career. He’d worked as a reporter for several local stations in Kansas and Missouri in the late 1970s.

“The tapes were from my first two jobs in television,” Crutcher says. “I was a news reporter, feature reporter, and I also produced weekend shows. [The tapes] had been sitting in a box for years — I took them with me every time I moved, but I never did anything with them. 

After retiring, Crutcher decided to begin working on a memoir. He realized that the tapes contained an important part of his production legacy.

“I thought it would be interesting just to see what I looked like back then — and maybe I’d find something that I could write about.”

Crutcher looked for a video digitization firm with U-matic experience.

“These were working tapes that had probably been recorded over multiple times, and they’d decayed for 40-something years,” Crutcher explains. “The condition worried me. I wanted to find someone who really knew what they were doing.”

“I looked all over the internet — I was afraid someone would put [the tapes] in a machine and they’d snap, or the tapes would gunk up the heads on a video deck.” 

While looking for a provider, Crutcher found Datarecovery.com and filled out an info request form. 

“Someone called me back immediately,” he says. “The thing I was most impressed by is how everyone seemed so eager to help.”

When he explained his concerns, he was put in contact with Datarecovery.com CEO Ben Carmitchel.

“I got a feeling that he really knew what he was doing.”

When Crutcher’s tapes arrived at the laboratory, the engineers went to work, repairing the degraded media and using several U-matic tape decks to obtain the best possible quality.

“I called for an update, and [Datarecovery.com] already had some of the videos ready,” Crutcher says. “Ben went way above and beyond. He edited footage together to bypass gaps in the tapes, which made it easier for me to have a final, finished product.”

While the digitization process was mostly straightforward, oxide loss had affected some of the tapes, diminishing their audio quality. 

“There were a few audio problems,” Crutcher says. “A producer I used to work with had a motto: ‘Audio will always bite you. But I knew the audio was there, it was just not getting through.”

By treating the tapes in a specialized environment with controlled heat and humidity, Datarecovery.com was able to restore most of the missing audio.

“We noticed the issue during one of the early transfers and quickly made adjustments,” Carmitchel explains. “With older tapes, you might not get a second chance to digitize, so the first attempt is extremely important.”

Datarecovery.com restored the videos, which included an interview with Chris Frantz of the Talking Heads.

We asked Crutcher for his opinion of the footage.

“It hurts, because I asked such stupid questions,” Crutcher says with a laugh. “I was just trying to explain to a general audience in rural Kansas — who the Talking Heads were and why they were important. But I was a fan — I’d seen them at CBGBs in New York in the mid-70s.” 

Crutcher has some advice for other video professionals with decades-old U-matic tapes: If the footage is important, digitize it. 

“At the time, broadcasters were concerned with reporting the news, not creating history,” he says. “Most TV news operations had very little archiving, so it was up to the reporter to keep the tapes of their work.”

“If you’re sitting on those tapes, get them to a professional,” he says. “I’ll be recommending Datarecovery.com to my colleagues.”
