dont think of it as double sided. (what happens when you have 17 heads?:))
dont think of it has half writte on one side, then half on the other. its alternated.
Code: Select all
instead of having
head0
AAAABBBB
head1
CCCCDDDD
you have
head0
AABBCCDD
head1
AABBCCDD

Tracks alternate sides of the platter. Since most reads of tracks will be consecutive, it allows you to read two tracks without having to move the heads. If you read an entire side, then the other you would have to move the heads twice as many times twice as far resulting in about twice the time to read an entire disk.
