LOCATION OF CUSTOMER CONTROLS Front Panel Emergency Eject Hole Disc Tray Stop/Eject Button Drive Activity Indicators 1. Disc tray This is the tray for the disc. Place the disc on the ejected disc tray, then lightly push the tray (or push the eject button) and the CD will be loaded. NOTE: Don’t pull out or push in the disc tray forcibly. This might cause damage to the loading section of the drive. 3. Emergency Eject Hole Insert a paper clip here to eject the Disc tray manually or when there is no power.
Rear Panel IDE Interface Connector Analog Audio Output Connector Jumper Connector Power Connector Digital Audio Output Connector NOTE: The actual drive may be different from this design. 1. Power Connector Connects to the power supply (5-and 12-V DC) of the host computer. NOTE : Be careful to connect with the proper polarity. Connecting the wrong way may damage the system (and is not guaranteed). Usually this connector can only be attached one-way. 2.

GLOSSARY ATIP Absolute Time in Pre-groove. With an additional modulation of the “Wobble”, the “Groove” contains a time code information. Wobble The pre-groove in the Disc is not a perfect spiral but is wobbled. With : – A typical amplitude of 30 nm – A spatial peried of 54~64 µm CW Continuous Wave. The laser light output is at a constant level. DOW Direct Over-Write. The action in which new information is recored over previously recorded information in CD-RW disc.

3. Disc Materials 1) CD-ROM disc • • • • It is composed of Silver _ colored aluminum plate and Reflective layer. Groove (Pit) of aluminum plate make a track. Laser wavelength : 780 nm, Laser Power (Read): 0.5mW Signal is detected by the difference of reflective beam intensity between “pit” and “Land” on the disc. Label Printing Protective Layer Reflective Layer Substrate (Polycarbonate) Pit Laser Beam 2) CD-R disc • It is so-called WORM (Write Once Read Many) CD.
3) CD-RW Disc Label Printing Protective Layer Dielectric Layer(TL) Recording Layer Dielectric Layer(UL) Substrate (Polycarbonate) Groove Laser Beam • It is composed of polycarbonate layer, alloy(silver, arsenic) layer, aluminum reflectivity layer, protective layer. • An crystalized alloy layer is transformed into noncrystalized by the laser heat. Therefore, writing and reading is enabled by the difference of reflectivity. • It is possible to overwrite about 1000 times.

8. Function of PCA and PMA area 1) PCA (Power Calibration Area) • PCA area is used to determine the correct Laser Power for a disc. – Method 1 : PCA area is divided by a track. – Method 2 : The previous Calibration value is referred. – Method 3 : ROPC is used to determine Laser Power value automatically in data writing. • CD-R Disc can write maximum 99 Tracks but CD-RW Disc can write unlimited tracks because it has a rewritable function.
2) ROPC (Running Optimum Power Control) • Variable primary factor of Optimum Power – Change of Power sensitivity on the Disc. (limited to 0.05 *Po) – Wavelength shift of the laser diode due to the operating temperature change. – Change of the Spot aberration due to the Disc skew, Substrate thickness, Defocus. Incident recording pulse – Change of Disc or Optics conditions due to the long term OPC ==> It is necessary to adjust continuously to obtain the Optimum Power.

2) Recording format using organic dye material (DVD-R/DVD+R) * The format that records data through the creation of recorded marks by changing the organic dye material with a laser beam.
3) Recording format using phase-change recording material (DVD-RW/DVD+RW) * Data is recorded by changing the recording layer from the amorphous status to the crystalline status, and played back by reading the difference of the reflection coefficient.
4. Writing Pulse Wave Form of DVD+R For different speed ranges, different write strategies can be used. This document specifies 2 options: - a pulsed write strategy, where each single mark is created by a number of subsequent separated short pulses. - a blocked write strategy, where each single mark is created by one continuous pulse.

Regional Code for DVD Disc – DVD-ROM drive transfers the regional code of the control data to host by the command of host, the DVD player of host reads the regional code, and plays title in the case of allowed regional code only. 2.
3. About Prevention the DVD-ROM from to be copy A data is able to encode and record in the disc, if a copyright holder wants to prevent the disc from copying. In case of a disc enhanced movie of 3 titles...... DISC KEY (2048 Bytes) is used to encode the whole contents in the disc and TITLE KEY (5 Bytes) is used to encode the title respectively. So, the data is encoded and stored in a disc through the unknown algorithms with a disc key and title key.

1-2. ALPC (Automatic Laser Power Control) Circuit ALPC function DVD/CD anlaog front-end IC(IC101 R2S35002) is for constant power control purpose. Based on the accurate power sensor(FMON) in P/U, ALPC feedback loop maintains constant power level against laser diode’s temperature variation. The ALPC loop amplifies(10x) the FMON signal to enhance the accuracy of read power level control. Swithching of amplification is made by combination of a logical WGATE signal and a logical RWAPC signal.

3-2-1. Tracking Servo The aim of tracking servo is to make laser beam trace the data track on disc. Tracking Error(TE) Signal is generated from tracking error detected block in R2S35002 using DPP(Differential Push-Pull) Method and DPD (Differential Phase Detection) Method. DPP Method uses not only main beam(A, B, C, D) but also side beam(EF1~EF4) for correcting DC offset generated in Push-Pull Method. The remaining procedure of TE signal processing in R8J32007 is similar to Focus Servo.

HW Self- Diagnostic function 1. Self-Diagnostic Function by LED Blink. • Basic operation: At JR6, MPU is included in DSP, MPU accesses each peripheral (inside, exterior) device, and discover a defect by the ability of a read/write of data to be performed correctly. Since MPU operates by the program with a built-in Flash-ROM, when abnormalities are in MPU, Flash-ROM, and these Data-Bus & control signals, this self-diagnostic function cannot be used.
2. LED does not blink at all at the time of a power supply injection. Eject-SW does not react. (1) Is it normal to the exterior Bus (Data-Bus, Address-Bus, control signal system) of MPU? Viewing — check: -- a short circuit, opening, etc. • The device connected to the exterior Bus of MPU in DSP, and its signal list Peripheral device Flash -ROM [Bus/Signal] (IC302) Address A1~A20 Data D0~D15 CS* CS0B WCK WR RCK RD => It repairs, when abnormalities are discovered.
3. Motor, Abnormalities in Actuator System The drive circuit of a motor & actuator consists of the three ICs IC601(R2S30202FP). The work of each IC is as follows. (1) IC601(R2S30202FP) : 7ch driver Spindle motor driver: 180° audio drive Type, an analog input, a PWM drive, a Vm=12V. Stepping motor driver X2: analog input, a PWM drive (differential), a Vm=12V Loading motor driver: Input/Output PWM drive, Vm=5V.
