Power mode, Active mode, Pre-idle mode | Fujitsu MCM3130AP guide

4.4 Various Processes

4.4.7.1 Power 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

4.4.7.2 Active mode

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

4.4.7.3 Pre-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.

4.4.7.4 Idle 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 s seconds (standard) to access media.

If no command is issued within a specified time (180 s) 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.
