3.4.3 Drive Ready Time
Ready
The condition in which the drive is able to perform a media access command (eg. read, write)
immediately. If a command is received during power on before ready, the drive ready time
becomes longer than the specified value.
Power On
This includes the time required for the internal self diagnostics.
3.4.4 Spindle Stop Time
The period from power off to complete stop of spindle is categolized as operating, and Operating Shock
criteria are applied until complete stop of spindle.
Refer to 6.9.3, “Operating Shock” on page 55.
3.4.5 Data Transfer Speed
Instantaneous disk-buffer transfer rate (Mbyte/sec) is derived by:
(Number of sectors on a track)*512*(revolution/sec)
Note: Number of sectors per track will vary because of the linear density recording.
