media ensures the highest track density available today. AMP uses
durable metal powder technology for recording at very high densities.
The back side of the AMP media contains specially formulated back-
coating to receive the optical servo tracks, so customers can reserve
the entire data-bearing side of the media for recording data and elim-
inate the need for pre-formatting.
