Floppy Drive Alignment Check
The floppy drive in the camera must be tested because it is subject to
more stress than those found in a stationary computer. When a drive is
jarred out of alignment, the unit will play and record its own discs but the
disc will not playback in a computer. The alignment boundaries can be
tested with these two test discs that are at the two limits of playability.
Replace the drive assembly if a test disc does not play but its own self-
recorded disc does play.
Floppy disc drive alignment is uneconomical because there are different
drives, each with different alignment jigs costing over $2,000. A floppy
drive assembly from the MVC-FD90 is about $142 (list price).

Procedure:
1. Disconnect the remote commander (RM-95) if plugged in.
2. Insert one of the two alignment discs.
3. Check one of the files to see if the picture is normal.
4. Remove the disc and perform the same test with the other disc.
5. Both discs should play back a normal picture. If only one disc plays,
the drive is just out of alignment. If both discs do not play either the
drive is severely out of alignment or there is something wrong with the
camera.
