 (1)
 QAR Functions The RZ bipolar data from the FDIU are received in the interface board and then switched to the respective magnetical record heat in the read/write board. Another weaker laser in the read/write board, reads the received data from the optical disk. The drive and control board controls the speed and direction of the disk motion. A BITE logic monitors the reel rotation, the disk speed and presence of data and disk. In case of discrepancies, the status output is received by the FDIU. The disk must be formatted to store the data.

 Change of the Optical Disk

 NOTE : The optical disk insertion is only possible when the recorder
____
 has power.

 The operational procedure to change the optical disk is as follows:
 -unlock and open the front door
 -press the EJECT pushbutton, the optical disk is automatically ejected
 -remove the optical disk
 -insert a new formatted optical disk gently into the aperture, (with the arrow on the left side).
 -close and lock the recorder door.
