Why bother with rewriteable disks? This is cold storage meaning that they will likely never throw this data away. I'd suspect Amazon's Glacier runs on something

  >Why bother with rewriteable disks? Its okay for Facebook and other single entities for backups. However for Glacier, it would mean throwing away the disk whenever someone deletes their data. It would also means constant replacement of disks.

Glacier is pretty fire-and-forget. > It would also means constant replacement of disks. They're already doing that with servers, why would disks be a problem?
