Good news for music and video pirates. Sony and Philips are to make CD
recorders that hold twice as much data as a conventional CD. Microchips which
let a CD player track tighter data spirals have already been developed. This
doubles disc capacity from 650 megabytes to 1.3 gigabytes. So a blank costing
less than $1 could hold 2.5 hours of CD-quality music, or hundreds of MP3
recordings, or a feature-length VHS quality movie. Double-density recorders are
expected to go on sale within six months. DD recordings will not play back on
existing CD players, but DD players will be able to play old CDs.
