A device enters the active mode under the following conditions:

∙A command with Seek or Write or Read is issued.

(2)Idle mode

In this mode, circuits on the device is set to power save mode. The device enters the Idle mode under the following conditions:

∙A IDLE or IDLE IMMEDIATE command is issued in the active or standby mode.

∙When one of following command is issued, the command is executed narmally and the device is still stayed in the idle mode.

–Reset (hardware or software)

–IDLE command

–IDLE IMMEDIATE command

–A command without Seek or Write or Read is issued.

(3)Standby mode

In this mode, the VCM circuit is turned off and the spindle motor is stopped.

The device can receive commands through the interface. However if a command with disk access is issued, response time to the command under the standby mode takes longer than the active or Idle mode because the access to the disk medium cannot be made immediately.

The drive enters the standby mode under the following conditions:

∙A STANDBY or STANDBY IMMEDIATE command is issued in the active or idle mode.

∙When automatic power down sequence is enabled, the timer has elapsed.

∙A reset is issued in the sleep mode.

When one of following commands is issued, the command is executed normally and the device is still stayed in the standby mode.

∙Reset (hardware or software)

∙STANDBY command

∙STANDBY IMMEDIATE command

∙A command without Seek or Write or Read is issued

∙CHECK POWER MODE command
