Host Interface

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.

4.4.7.5 Standby mode

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

4.4.7.6 Sleep mode

Sleep mode uses power consumption as standby mode. To set the ODD in sleep mode, the host must issue the Sleep command. To restore the ODD from sleep mode, hardware reset or software reset is required. The host must not issue any command after the Sleep command. The ODD requires 15 s (standard) to respond.

4.4.7.7 Standby timer

The standby timer is used to count the time during which the host issues no command.

The standby timer value is programmable with the Power Condition Page of the MODE SELECT command. The default value is 32 minutes (including the transition time to idle mode).
