1-1. Physical layout compared to CD
min Φ33
The conventional CD and CD-R discs basically have the same
physical layout. However, as you can see from the Fig. 1,
comparing to the conventional CD, the CD-R disc also has socalled “minus” areas such as PCA (Power Calibration Area) and
PMA (Program Memory Area) where the temporary information
is recorded.

• Partially recorded disc
The CD-R system gives the opportunity to record a disc in several
actions at a different time on a different recorder. After the first
recording, the information area is divided into five parts as shown
below and in the right.
1: Power Calibration Area (PCA)
2: Program Memory Area (PMA)
3: Lead-in Area
4: Program Area
5: Lead-out Area
• Finalized disc
After finalizing the disc, the CD-R disc will become compatible
with the RED Book (for regular CD) definitions and specifications.
Therefore, it can be played back on conventional CD players. The
Information Area of a finalized disc consists of three parts:
1: Lead-In Area

1-2. Pregrooved track wobbling + ATIP
When manufacturing the CD-R disc, it has been ÒpregroovedÓ. This pregroove in the CD-R disc is not a perfect spiral but
is wobbled so that the CD-R disc can be recognized by a CD-R recorder even when it is completely blank.
It has many purposes. It not only helps keep the servo on an exact tracking of outgoing spiral but also the demodulated
wobbling frequency contains the time information in digital format (21.05 kHz = Ò0Ó, 23.05 kHz = Ò1Ó). These frequencies
have been selected so that the mean frequency is equal to Fs / 2 (= 22.05 kHz). Also the interleaved is the manufacturer's
measured default laser power level.

1-3. PCA + consequence
Each recorder has a tolerance in the laser power and the dye from different manufacturers varies. In order to optimize the
recorder / disc combination, there is a PCA (Power Calibration Area) included in the CD-R disk. This area consists of two
parts, the Count Area and Test Area. In the Test Area, test recordings are made, stepping through several power levels. After
playing back the recorded test signal, the optimum level is automatically determined. This value is memorized until the disk
tray is opened. The Count Area keeps the track on how many of the test areas have been used indicating where to start the
next test. The PCA is designed to accommodate for 100 tests. When the PCA is full, the default value written in the wobbled
groove is used instead.

CAUTION :
Every time the CD-R disc is inserted, one test is performed. Also if you leave the disc in the recorder at power off, a test will
be performed when powering on. This might lead to the situation that the PCA might be fully used up even if there is a
remaining space to record audio signal. The recordings made after the PCA is fully used up will not be optimal in performance.

Fig. 4 Cross Section of CD-R disc
During recording, the laser is tracing the wobbled groove. When a pit is to be recorded, the laser fires off a high power beam
and the organic dye will become black and deformed. This is the way a Ònon-reflectiveÓ part is created. When a groove is
to be recorded, the laser is not fired and the high-reflective surface is maintained. If the data word contains successive the
same information (e.g. 111 or 000), the pit will be continuous. When the data word contains changes, the pit - groove status
will also change.
• Recording Principle
A high power laser beam is shot.
• Playback Principle
NO PITS
A low power laser beam is shot
and high reflectance is obtained.
Organic dye becomes black
and pit is created.
ON PITS
A low power laser beam is shot
and only low reflectance is obtained.
Fig. 5 Recording & Playback Principle
1-5. Finalize
In order to be playable on an ordinal CD-player, the CD-R disc must have a corresponding data for TOC (Table Of Contents).
This area is not used until all the recording is completed. Instead, a special area called PMA (Program Memory Area) is used.
When the disk is full or all the recording is completed, the disk can be finalized. This means that the temporary information
in the PMA is checked and transferred to TOC. Now the disk is playable on an ordinal CD player but it will not be recordable
any more.

[ How to find the null point ]
When you insert the small screwdriver into the slit for the grating adjustment and change the grating angle, the amplitude
of the tracking error signal at CN104 (TP1), Pin 3 (TE) changes. Within the range for the grating, there are five or six
locations where the amplitude of the wave reaches a minimum. Of these five or six locations, there is only one at which
the envelope of the waveform is smooth. This location is where the three laser beams divided by the grating are all right
above the same track. (See Fig. 13.)
This point is called the null point. When adjusting the grating, this null point is found and used as the reference position.

8-3. Judging Method of Unit
1. Look into the symptom thoroughly
• Check the location of fault (optical, electrical or mechanical system).
• Check if the disk is okay or faulty.
• Check if external unit connected to the CR200 is faulty.
2. Remembering the operation flow chart
Example of fault : The CR200 does not play.
• If the initial operation is completed.
• If the pickup is at initial position.
• If the laser diode is lighting.
• If the LD ON signal is output.
• If the lens is making the sweep operation.
• If the spindle is rotating.
• If the spindle is locked.
• If the FG signal is output.
• If the proper laser power is output.
• If the RF signal (eye pattern) is clear.
8-4. Judging Method of Pickup
Item
If the slider operation is normal ?
Check if the laser diode is lit.
Check if the lens is moving up/down.
Checking Method
• Check the slider circuit and mechanism in the TEST mode.
• If not, check the LD ON signal.
• If the lens is dirty, clean it and check the RF level before and after cleaning.
• If not, check the actuator, FSC and TRK coil.
• Check if the actuator is bent by the contact with cleaning disc, etc.,
