I also seem to remember the disks are 400K single sided and go in the
The exact capacity depends on the format and encoding method. Each disk
is single-sided, 80 cylinders, soft sectored. It's similar ot a PC 360K
disk but with all 80 tracks on one side (A PC 360K disk is 40 cylinders, 2
hears, of course)
drive in opposite direction so you need to remember
the orientation of
the floppies.
Indeed. There are actually good emchancial reasons for this.
The mechanism is built o na metal chassis in the middle of the drive.
There's a disk hub on each side, the spindle motor lies horizontally at
the front, a belt links them all up. The head postioner stepper is at the
rear, it has a ledschre mechansim that moves a head carriage with the
head for each disk on it.
So for easy of head mounting ,the active surface of each disk is closest
to the midle of the drive. And that's the side without the label on the
disk. So the labels face outwards in both cases.
