• 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.
