Standby mode automatically after the drive has been inactive for a specifi-
able length of time. The standby timer delay is established using a Standby
or Idle command. In Standby mode, the drive buffer is enabled, the heads
are parked and the spindle is at rest. The drive accepts all commands and
returns to Active mode any time disc access is necessary.
• Sleep mode
The drive enters Sleep mode after receiving a Sleep command from the
host. In Sleep mode, the drive buffer is disabled, the heads are parked and
the spindle is at rest. The drive leaves Sleep mode after it receives a Hard
Reset or Soft Reset from the host. After receiving a reset, the drive exits
Sleep mode and enters Standby mode with all current translation parameters
intact.
• Idle and Standby timers
Each time the drive performs an Active function (read, write or seek), the
standby timer is reinitialized and begins counting down from its specified
delay times to zero. If the standby timer reaches zero before any drive activity
is required, the drive makes a transition to Standby mode. In both Idle and
Standby mode, the drive accepts all commands and returns to Active mode
when disc access is necessary.
