MC104S  SPECIFICATIONS(Dec. 22 , 1999)I - 1(Preliminary)I. OUTLINE1. OverviewThe Compact Disc Recordable/ReWritable Auto Changer drive MC104S can do muchmore than read and write the usual CD-R discs. When you load it with a rewritableCD-RW disc, you can record, read, and edit any kind of data, because these discsallow you to rewrite information that has already been recorded.2. Features1)  Running OPC*1 gives a flatter writing signal that improves reliability. 2)  An improved anti-heat design means that no cooling fan is needed.3)  Uses the world standard SCSI interface. 4)  Can read not only CD-R and CD-RW discs, but also video CDs, music CDs,and photo CDs.5)  Half-height space but a great capacity. 6)  Conforms to the world standard Orange Book Part II (CD-R) and Part III (CD-RW). Can use “TRACK AT ONCE”,  “DISC AT ONCE”,  “MULTISESSION”,“PACKET WRITE” and “SESSION AT ONCE”.7)  Supports packet write for easy writing to CD-R and CD-RW discs.*1 Continuously monitors the signal level during recording and adjusts the laserpower to compensate when the disc is dirty, insuring a flat signal.

MC104S  SPECIFICATIONS(Dec. 22, 1999)II - 4(Prelininary)2.1. DoorThis is the door to insert the magazine. Place discs on disc trays of the magazine,then insert the magazine and the CDs will be loaded. The system need to beinstalled the driver to load discs on disc trays of the magazine. The only lowestdisc in the magazine is loaded if the driver would not be installed. ! -  Don’t use force to pull out or push in the magazine. This might causedamage to the loading section of the drive.2.2. Eject ButtonThis is the button used to eject or bring in the disc tray.2.3. Busy indicatorThis indicator light shines green when power is on.  When the disc tray or disc isbeing accessed, the light shines or flashes orange.  Even when a disc is loadedor a disc is not being accessed, the light shines green.  When a illegal disc isloaded or some hardware trouble occurs, the indicator blinks.2.4. Headphone JackThis jack is for connecting headphones or mini-speakers.2.5. Volume controlThis is used to adjust the output volume of the headphone jack. It can’t be usedto adjust the output volume for the audio output connectors on the rear panel.2.6. Power ConnectorUsed to connect to the host computer’s power supply (DC 5V / 12V) ! - Be careful not to reverse the poser connector when attaching it. A reversedconnection may cause damage to the equipment (not covered by thewarranty).2.7. SCSI ConnectorUse a 50 pin double-end flat SCSI cable to connect to the SCSI interface. ! - Connecting or disconnecting connectors while power is on may result in ashort circuit, causing damage to the equipment. When connecting ordisconnecting connectors, make sure to turn off the power beforehand.2.8. Analog Audio Output ConnectorUsed to connect to the sound card.2.9. Jumper ConnectorUsed when selecting the SCSI ID number and terminator. SCSI ID and terminatorchanges become valid after power is turned off, then on again. ! - If two peripheral devices use the same SCSI ID number, it will cause thehost computer to operate abnormally or fail to start up.

Also,when multiple peripheral devices are connected, this drive needs a terminator if itis the last in the line.The terminator of this product can be set by installing (terminator: ON) or removing(terminator: OFF) the jumper pin from the jumper connector.
MC104S  SPECIFICATIONS(Dec. 22, 1999)III - 1(Preliminary)III. SPECIFICATIONS1. Functionality1.1. RecordingData should be recorded on the optical disc in response to host computercommand.1) Drive receives necessary information such as logical block address, number ofblock and data to be recorded from the host computer.2)  Recording to pre-recorded area can not be executed. (CD-R disc)3)   Overwriting to pre-recorded area can be executed. (CD-RW disc)1.2. ReadingData on optical disc should be read in response to the host computer command.Audio playing (CD-DA) can be executed when receiving the Audio playingcommand from the host computer.1.3. Load / Eject of Disc1) LoadPlace discs on disc trays of the magazine, then insert the magazine and the CDswill be loaded. The system need to be installed the driver to load discs on disctrays of the magazine. The only lowest disc in the magazine is loaded if thedriver would not be installed.2) EjectOperator can eject the magazine (discs) by pushing this button.1.4. Spindle Motor Start / StopThe controller of the drive senses the disc to be set on the turn-table connectedwith the spindle motor and then starts to rotate the spindle motor, in response tothe host computer command1.5. Seek MotorThe controller of the drive starts to move the optical pick up carriage, in responseto the host computer command.1.7. Eject ButtonOperator can eject the magazine (discs) by pushing this button.1.8. Busy indicatorThis indicator light shines green when power is on.  When the disc tray or disc isbeing accessed, the light shines or flashes orange.  Even when a disc is loadedor a disc is not being accessed, the light shines green.  When a illegal disc isloaded or some hardware trouble occurs, the indicator blinks.
