Good storage could keep cassette tapes playing for decades
Engadget says cassette tapes may last about 30 years under ideal conditions, but heat, moisture and other hazards can shorten their life to as few as five years.
Cassette tapes may survive for decades if stored carefully, according to Engadget, which says their commonly cited lifespan of about 30 years is only a general estimate based on ideal conditions.
Heat, cold, temperature fluctuations and humidity can accelerate deterioration. Engadget recommends keeping tapes in a cool, dry environment, at approximately 15–23°C and 25–55 per cent humidity, away from sunlight, moisture, dust, pests and magnetic fields.
Tapes should remain in protective cases, with their exteriors cleaned periodically. Engadget also advises cleaning the heads of cassette players and playing tapes occasionally, as the binder coating can become sticky when tapes are left unused.
Rewinding tapes after listening may help limit stress and uneven winding. Under poor storage conditions, Engadget says their lifespan could fall from about 30 years to as few as five, while the possibility of reaching 100 years with proper care is presented only as theoretical.
For recordings that carry personal or historical value, digitisation may offer another preservation route. Tapes can be transferred through a digitisation service or recorded to digital files using a computer and suitable software before deterioration worsens.
