It appears as if the Eliezer S. Yudkowsky <> wrote:

It also appears as <> commented:

\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ Professor Ted Williams at Keele University in the UK has developed a solid state memory system with a capacity of several times more than is possible using current hard disks. The system is based on the magneto-optical technology used for reading CD-Roms, and has a capacity of 86GB per sq cm. However, it uses a different operating approach. As the new high data-density substrate used can be put on virtually any surface, the applications for the system include computer and processor memory, particularly with palmtops, credit cards and smartcards, where space is at a premium. \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ [Source: Financial Times, 22/10/97, p.16.]

Do not magneto-optical media have lower read-write times than magnetic media?
