1. iD PHOTO DISC 1-1. iD PHOTO DISC HIGH-DENSITY TECHNOLOGY 1-3. CAD ULTRA-HIGH MAGNETIC RESOLUTION METHOD The iD Photo Disc has a diameter of 5 centimeters and yet it can store up to 730MB of information. A laser pulse magnetic field modulation recording method and CAD-type ultra-high magnetic resolution method have been used to record data at a track pitch of 0.6 µm and an extremely short mark length of 0.235 µ, which is smaller than the spot diameter of the laser beam.
1-4. PRML SIGNAL PROCESSING When the data on the iD Photo disc is read, the 0.235 µm overlapping recording marks which are made during laser pulse magnetic field modulation recording are read through an 0.6 µm window by means of a CAD-type ultra-high magnetic resolution reading method. Because this window has a diameter of 0.6 µm, at least two or three recording marks can be viewed through this window at any given time.
2. OUTLINE OF iD FORMAT DISC DRIVE CIRCUIT 1. OUTLINE OF DRIVE CIRCUIT BOARD A drive part is composed of the block diagram of the Fig. 1, and a drive circuit board is composed of MC1, MC2 and MC3.
2-3. OUTLINE EXPLANATION FOR EACH BLOCK OF DRIVE CIRCUIT BOARD (MC3) 2-3-1. SERVO AMPLIFIER 1. FOCUS SERVO (DISC SURFACE RUNOUT TRACKING CONTROL) Servo control is carried out by the DSP which is built into the ASIC (IC402). This controls the focus actuator of the pickup in order to carry out surface runout tracking control. They are amplifier part for the focus servo and the tracking servo. Minute amplitude The S-shaped curve amplitude of the focus error signal (FE signal) is TYP 1.
3. Balance adjustment of main PP and sub PP This measures the DC offset when shifting to the inside and to the outside occurs, with respect to the center of the TE signal when the actuator is shifted 0.83 V to the outside, when it is shifted 0.83 V to the inside and when it is at the standard position. 1.
the FCM signal or the address signal. These LC filters remove almost all of the signal components which are at 20 MHz or above, leaving just the base frequencies (2-3 MHz) for the FCM and address signals. 3. The principle of rec/play clock generated by the PLL The clock is reproduced by the PLL with respect to the signal which has been detected to be the FCM signal by the circuit (primary function circuit) which generates the slice level from the FCM signal. The frequency of the reproduced clock is 20 MHz.
APC IC (on the pickup) The APC IC functions to maintain the current detected by the photosensor attached to the laser to a constant level. This has the effect of canceling any fluctuations in characteristics resulting from the semiconductor laser temparature, and any variances in production lots, so that the laser power can be maintained at a stable level. The ON/OFF laser high-frequency currents, power save and laser are output open corrector from LPC IC, and input to APC IC.

3. IC902, IC904, IC908 (H Driver) and IC907 (V Driver) 4. IC905 (CDS, AGC Circuit and A/D Converter) An H driver and V driver are necessary in order to generate the clocks (vertical transfer clock, horizontal transfer clock and electronic shutter clock) which driver the CCD. IC902, IC904 and IC908 are inverter IC which drives the horizontal CCDs (H1 and H2).
5. Transfer of Electric Charge by the Horizontal CCD The transfer system for the horizontal CCD emplays a 2-phase drive method. The electric charges sent to the final stage of the horizontal CCD are transferred to the floating diffusion, as shown in Fig. 1-6. RG is turned on by the timing in (1), and the floating diffusion is charged to the potential of PD. The RG is turned off by the timing in (2). In this condition, the floating diffusion is floated at high impedance.

Scannning converter (Interlace converter) This circuit uses the function of a 64-Mbit SDRAMs to convert the non-interlaced signal which is output from the CCD into an interlaced signal for the video monitor. 1-2. Camera signal processor This comprises circuits such as the digial clamp circuit, white balance circuit, γcircuit, color signal generation circuit, matrix circuit and horizontal aperture circuit. 1-8.
3. LCD Block During EE, gamma conversion is carried out for the 10-bit RGB data which is input from the A/D conversion block of the CCD to the ASIC in order that the γ revised can be displayed on the video. The YUV of 640 x 480 is then transferred to the SVRAM. The data which has accumulated in the SDRAM is after D/A conversion is carried out by SDRAM control circuit inside the ASIC, makes Y/C signal, the data is sent to the LCD panel and displayed.

3-5. ST1 STROBE CIRCUIT DESCRIPTION 1. Charging Circuit 2. Light Emission Circuit When UNREG power is supplied to the charge circuit and the CHG signal becomes High (3.3 V), the charging circuit starts operating and the main electorolytic capacitor is charged with high-voltage direct current. However, when the CHG signal is Low (0 V), the charging circuit does not operate. When RDY and TRIG signals are input from the ASIC expansion port, the stroboscope emits light. 2-1.
