Appendix A APPENDIX A PIONEER CD-ROM DRIVES - AUDIO FUNCTIONS The CD-ROM drives consist of two logical subsystems - a CD reader and a controller. The controller receives SCSI commands, and sends commands to the reader for execution as needed. This allows audio commands to be executed in the background. At times, the two subsystems may be operating independently. In addition to the normal audio commands, the CD-ROM drives support the Pioneer Laser Disc Player control commands.
