4.4.7.1Power mode

The ODD supports power modes shown below. The ODD uses a power mode equivalent to standby mode, except that the DRDY bit is 0 while media is not mounted.

!Active mode

!Pre-idle mode

!Idle mode

!Standby mode

!Sleep mode

4.4.7.2Active mode

In active mode, all circuits are enabled. The ODD requires the shortest time to start processing a command.

4.4.7.3Pre-idle mode

In pre-idle mode, the read/write circuits stop. The ODD can receive a command from the host, but since some circuits stop, the command requires 20 ms to access media.

The ODD automatically enters pre-idle mode if no command is issued within a specified time (0.5 second) in active mode. When it receives an access command, the ODD automatically enters active mode. The pre-idle mode cannot be controlled from the host computer.

4.4.7.4Idle mode

In idle mode, the servo and read/write circuits stop. The ODD can receive a command from the host, but because some circuits stop, the ODD takes 1.0 seconds (standard) to access media.

If no command is issued within a specified time (180 seconds) in active mode, the ODD automatically enters pre-idle mode, then enters idle mode. When it receives an access command, the ODD automatically returns active mode. The Idle Immediate command can shift the ODD from active mode or standby mode to idle mode.

4.4.7.5Standby mode

In standby mode, the spindle mode stops. The ODD can receive a command from the host, but since the spindle motor stops, the recovery to access media takes 5 seconds (standard).

The ODD automatically enters standby mode from active mode if no command is issued within a specified time when the standby timer is enabled. When it receives a command, the ODD automatically returns active mode. The Standby Immediate command can also directly shift the ODD from active or idle mode to standby mode.
