Datasheet

7.5.3 Connector
See Section 8.2, “Interface Connector” on page 33.
7.5.4 Mounting orientation
The drive will operate in all axes (360°).
Performance and error rate will stay within specification limits if the drive is operated in the other permis-
sible orientations from which it was formatted. Thus a drive formatted in a horizontal orientation is able to
run vertically and vice versa.
Vibration test and shock test are to be conducted by mounting the drive to the test table using a special
fixture.
7.5.5 Load/Unload mechanism
The head load/unload mechanism is provided to protect the disk during shipping, movement, or storage.
Upon power down, a head unload mechanism secures the heads at the unload position. See
Section 7.6.4, “Nonoperating shock” on page 28 for additional details.
7.6 Vibration and shock
All vibration and shock measurements in this section are for the drive without the mounting attachments
for the systems. The input level is applied to the normal drive mounting points.
7.6.1 Operating vibration
The drive will operate without a hard error while being subjected to the following vibration levels.
7.6.1.1 Operating random vibration
The test consits of 30 minutes of random vibration using the power spectral density (PSD) levels
specified in C-S 1-9711-002 (1990-03) as V5L. The vibration test level for V5L is 0.67 G RMS.
