7.7.4.1 Drive mounting
The drive will operate in all axes (6 directions). Performance and error rate will stay within specification
limits if the drive is operated in the other orientations from which it was formatted.
The recommended mounting screw torque is 0.6 - 1.0 [ Nm] (6 - 10 [ Kgf.cm]). The recommended
mounting screw depth is 4 [ mm] Max for bottom and 4.5 [ mm] Max for horizontal mounting.
To avoid performance degradation, mount the drive in the system securely enough to prevent
excessive motion or vibration of the drive at seek operation or spindle rotation, using appropriate
screws or equivalent mounting hardwares. Consult with the issuer of this specification for actual
application if necessary.
Drive level vibration test and shock test are to be conducted with the drive mounted to the table using
the
bottom four screws.
7.7.5 Heads unload and actuator lock
Heads are moved out from disks (unload) to protect the disk data during shipping, moving or storage. At
power down, the heads are automatically unloaded from the disk area and the head actuator locking
mechanism will secure the heads in the unload position.
7.7.6 Breather hole
The breather hole must be kept clear and unobstructed at all times. Do not cover the breather hole.
