Disks

Each DE contains disks whose external diameter is 95 millimeters and internal diameter is 25
millimeters. The DE for the MAF3364FC, MAG3182FC and MAG3091FC contains 10, 5 and 3
disks respectively.
Each time disk rotation stops, the read-write heads touch the disk surfaces. Disk surfaces
withstand at least 10,000 head touch operations at disk rotation start and stop.

The read/write head configuration is shown in Figure 5.1.
There are 19 read/write heads in the MAF3364FC, 10 in the MAG3182FC and 5 in the

These heads float up from the surface of the disk automatically when the spindle motor's speed
has reached a certain speed.
