6.4.4 Mounting orientation The drive will operate in all axes (six directions) and will stay within the specified error rates when tilted ±5degrees from these positions. Performance and error rate will stay within specification limits if the drive is operated in the other permissible orientations from which it was formatted. Thus a drive formatted in a horizontal orientation will be able to run vertically and vice versa. The recommended mounting screw torque is 3.0±0.5 kgf-cm. The recommended mounting screw depth is 3.0±0.3 mm for bottom and 3.5±0.5 mm for horizontal mounting. The user is responsible for using the appropriate screws or equivalent mounting hardware to mount the drive securely enough to prevent excessive motion or vibration of the drive at seek operation or spindle rotation. 6.4.5 Load/unload mechanism The head load/unload mechanism is provided to protect the disk data during shipping, movement, or storage. Upon power down, a head unload mechanism secures the heads at the unload position. See Section 6.5.4, "Nonoperating shock" on page 35 for additional details. 6.5 Vibration and shock All vibration and shock measurements in this section are for drives without mounting attachments for systems. The input level shall be applied to the normal drive mounting points.Vibration tests and shock tests are to be conducted by mounting the drive to a table using the bottom four mounting holes. 6.5.1 Operating vibration The drive will operate without a hard error while being subjected to the following vibration levels. 6.5.1.1 Random vibration The test consists of 30 minutes of random vibration using the power spectral density (PSD) levels below. The vibration test level is 6.57 m/sec2 RMS (Root Mean Square) (0.67 G RMS).

Travelstar 80GN Hard Disk Drive Specification

6.4.4

Mounting orientation

The drive will operate in all axes (six directions) and will stay within the specified error rates when tilted ±5degrees

from these positions.

Performance and error rate will stay within specification limits if the drive is operated in the other permissible ori-

entations from which it was formatted. Thus a drive formatted in a horizontal orientation will be able to run verti-

cally and vice versa.

The recommended mounting screw torque is 3.0±0.5 kgf-cm.

The recommended mounting screw depth is 3.0±0.3 mm for bottom and 3.5±0.5 mm for horizontal mounting.

The user is responsible for using the appropriate screws or equivalent mounting hardware to mount the drive

securely enough to prevent excessive motion or vibration of the drive at seek operation or spindle rotation.

6.4.5

Load/unload mechanism

The head load/unload mechanism is provided to protect the disk data during shipping, movement, or storage. Upon

power down, a head unload mechanism secures the heads at the unload position. See Section 6.5.4, “Nonoperating

shock” on page 35 for additional details.

6.5

Vibration and shock

All vibration and shock measurements in this section are for drives without mounting attachments for systems. The

input level shall be applied to the normal drive mounting points.Vibration tests and shock tests are to be conducted

by mounting the drive to a table using the bottom four mounting holes.

6.5.1

Operating vibration

The drive will operate without a hard error while being subjected to the following vibration levels.

6.5.1.1

Random vibration

The test consists of 30 minutes of random vibration using the power spectral density (PSD) levels below. The

vibration test level is 6.57 m/sec

RMS (Root Mean Square) (0.67 G RMS).
