For decades, communities have recorded stories, songs, and teachings on analog tape formats, like reel-to-reel tapes and cassettes. Yet, over time, these tapes start to degrade, threatening the content stored within. Talking Owl Technologies works at the intersection of technology and tradition, helping to digitize and preserve these invaluable resources. But before digitization, it’s essential to assess the state of these tapes. Here’s how you can spot signs of degradation, understand what they mean, and take steps to protect your content.

Understanding Analog Tape Degradation

Analog tapes are susceptible to damage from environmental factors, particularly humidity and temperature. Physical and chemical changes occur in tapes stored in damp or overly dry environments. These changes can make it difficult, or even impossible, to recover their contents.

The most common signs of tape degradation include:

1. Sticky-Shed Syndrome (SSS): This is one of the most common forms of degradation, affecting reel-to-reel tapes especially. Tapes suffering from SSS will feel sticky to the touch and can emit a foul, musty odor. This happens when the binder, which is the glue holding the magnetic particles to the tape, absorbs moisture. It becomes sticky, often due to prolonged storage in a humid environment.
2. Powdering and Shedding: In dry environments, tapes can lose their flexibility, becoming brittle or flaking. Powdering shows as a fine dust on the surface of the tape. Shedding can cause the magnetic layer to separate from the tape base. Sometimes it looks as dark flakes. This issue is exacerbated by extremely dry conditions, which can lead to permanent loss of the magnetic material.
3. Warping and Curling: Excessively dry conditions can cause tapes to curl or warp. This deformation makes playback nearly impossible. The tape can no longer sit flat on the playback heads of a machine. Additionally, tapes stored in high humidity can develop uneven edges, causing them to skew during playback.
4. Mold Growth: Tapes stored in humid, warm conditions are especially prone to mold growth. It appears as fuzzy patches or specks on the tape. Mold is highly damaging and difficult to remove without specialized equipment. Playing a moldy tape without proper cleaning can contaminate playback devices.

Assessing Analog Tape Condition

Before handling your tapes, take a close look at them for the subsequent signs:

• Sticky Feeling or Smell: Gently hold a tape, checking for a sticky texture or musty smell. These show moisture-related issues, such as Sticky-Shed Syndrome.
• Dust or Flaking: Examine the tape for dust-like particles or flaking, which suggest binder degradation in dry conditions.
• Warping or Curling: Look for any curling or warping along the edges. If the tape won’t lie flat or appears uneven, it may be warped.
• Mold: Visually inspect the tape for any signs of mold. Mold often appears as small white, green, or black spots and should not be handled directly.

Once a tape shows visible signs of damage, handling it improperly can make matters worse. For instance, if you play a degraded tape in a standard tape deck without assessment, it can permanently damage the tape. This action can also harm the playback device.

Preserving and Digitizing Language Recordings

Here are the steps to follow to protect your analog tape materials and ensure they can be digitized successfully:

1. Minimize Handling and Store Carefully: Limit handling as much as possible. Keep tapes in a cool, dry location, ideally with temperatures between 60-70°F and 35-45% humidity. Avoid basements, attics, or any place with significant temperature or humidity fluctuations.
2. Avoid DIY Cleaning and Repairs: While it may be tempting to clean or repair a degraded tape on your own, DIY efforts can worsen the damage. Specialized cleaning, often using equipment designed for delicate media, is usually required.
3. Consult a Professional for Assessment: If you notice signs of degradation, contact a professional preservation or digitization company like Talking Owl Technologies. Our team can assess the condition of each tape and recommend a preservation strategy.
4. Consider “Baking” for Sticky Tapes: Tapes with Sticky-Shed Syndrome can sometimes be temporarily stabilized by a process called “baking” (controlled heating). However, this process should only be conducted by professionals, as overheating can cause irreversible damage.
5. Digitize at the Earliest Opportunity: Analog tapes have a limited lifespan. Digitization not only allows for the preservation of Indigenous language recordings in a stable format but also makes them accessible for future generations. Talking Owl Technologies provides specialized digitization services, capturing audio with the utmost care to retain its quality and authenticity.

The Future of Language Preservation

For Indigenous language preservation, each recording holds the potential to revive and pass down language, stories, and wisdom to future generations. But as time wears on, these analog recordings become increasingly fragile. By carefully assessing and preserving tapes today, we can safeguard this invaluable cultural heritage for years to come. If you have materials in need of preservation, reach out to Talking Owl Technologies. Our experts can guide you through the process, ensuring these cultural treasures are preserved for future generations.
