A drive's sectors actually start out on the rim of the drive. In that
area, you have more sectors per track (outer rim) than as you go closer
towards the spindle. At the spindle you have the lowest sectors per
track. Both the data rate and the sectors per track are greatest at the
rim of the hard drive; which is where the boot sector is too btw. The
heads can stay on one track and transfer more contiguous data per
cylinder on cylinders at the rim than they can close to the spindle.
All this analysis is valid except in my experience the recording on a
hard disk gets nowhere really close to the spindle for obvious reasons.
Only the outer sections of the disk are recorded on.
