[comp.arch] Slow CD ROMS?

According to the Byte article (sometime in the last year) the reason head
seeks are so slow is that the mass of the head is currently much  greater.
But efforts are being made to remove the active parts from the head. If it
can be made as light as a hard drive head, then it essentially IS a hard drive
head as far as speed goes. Already, there is very little difference in the
burst reading speed (well, that can't be explained by the lower rotational
speed).

I would think that a fiberoptic-piped read/write head would be practical and
popular within 5 years.

p.s. Maxtor's unit stores 800 Meg, and has an access time of 130ms. Not good
compared to hard disks, but faster than most others, and possibly comparable
to a floppy.
