DVD Disc Rot & Hospital Superbugs

In regards to how long a typical DVD’s life expectancy is, Sony’s official statement is that “A typical DVD disc has an estimated life expectancy of anywhere from 30 to 100 years when properly stored and handled.” That’s a pretty substantial 70-year gap in terms of possibilities, but as we hurtle towards the 30th anniversary of the introduction of DVDs in 1996,(click)

Disc Rot...

It seems all spinnable drive media

suffer from some form of it.

The early hard drives were notorious

for eventual bearing failures,

and head crashes.

Technological obsolescence

is a nagging worry as well ...

LP records and high-fidelity playback

systems are becoming rare.

Cassette tapes ?

Try to find one...

The advent of music CDs seemed

to be a solution, until they stopped

putting CD drives in PC's ...

DVDs seemed like a panacea.

Huge storage capacity, enough

for feature films. Laser playback,

so wear was not a concern.

Until now.

I read this book in the '70s...

It concerned me.

The team traced the plastic-eating trick to a single enzyme, which they named Pap1. In laboratory tests, Pap1 reduced a thin PCL film by seventy-eight percent within seven days. The bacterium then used the liberated fragments as its sole carbon source.

Try plating the film with SILVER... -Chuck
