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) PMA (Program Memory Area)

• It has a track information (track No, track Start/End time) of every track before writing completed. – PMA area has the last written point and the next writable point of a disc. – In case of CD to CD copy, some writer may not write PMA area.

* When Disc is Finalized,

PMA information is transferred to the Lead_In area so that general Driver can read it.

* Because PCA and PMA area exist before Lead-In area, General CD Player or CD-ROM Drive can’t read

these areas.

9. OPC and ROPC

1) OPC (Optimum Power Control)

• This is the first step of writing process, because CD writer has its own laser power value and media have different writing characteristics,

– This is determined by the Writing characteristic, speed, temperature, and humidity. – Laser wavelength is determined by the environmental temperature (775~795nm) and Optical Laser Power is

determined by the test and retry.

• Asymmetry and optimum writing Power

– EFM signal Asymmetry is determined by the writing power.

Therefore, Optical Power which has the same value to the preset power value can be estimated by measuring HF signal Asymmetry on the PCA area.

• Measurement of Asymmetry

* Parameter setting (Beta) : Using AC coupled HF signal before equalization

Beta = (A1+A2)/(A1-A2)

Time

P << Po

P = Po

Page 27

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.

– Change of Disc or Optics conditions due to the long term OPC

==> It is necessary to adjust continuously to obtain the Optimum Power.

• Principle of Running OPC – To meet the factors mentioned above,

a horizontal _ direction movement of a curve is uesd.

– Beta = f(B-level) = constant on the Recorded Disc – Procedure of ROPC

a. Reference B-level is determined during OPC Procedure. b. During Recording, B-level value is controlled to have a close

Reference B-level value.

c. Normalization of B-level is used to eliminate the effect of reflectivity fluctuation.

==> The reflected B-level value is normalized by the disc reflectivity itself.

> Disc structure

[Recording] Recording is done by changing the organic dye layer and the substrate with a laser when a strong is applied to a disc, the temperature of the ortanic dye material goes up, the dye is decomposed and the substrate changes at the same time. At this time, a durable bit is created as is the case with a CD-ROM.

[Playback]

Signals are read with the differences of the reflection of a laser from pits.

3) Recording format using phase-change recording material (DVD-RW/DVD+RW)

[Recording] When a high-power laser is applied to the recording material, it melts and then becomes amorphous with a low reflection coefficient when it quickly cools off. When a mid-power laser is applied to heat gradually the recording material and then gradually cools it off, it becomes crystal with a high reflection coefficient.

[Playback] A low-power laser is used for playback. The amount of reflected light depends on the status (amorphous or crystalline) of the recording material. This is detected by an optical sensor.

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.

2. Copy Protection and Regional Code Management Block

Block Diagram

Brief Process

1. 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. Management of DVD Disc for the scrambled of data

(1) DVD-ROM and DVD player of host generate the “KEY 1” respectively, transfer to opposite part, the

“KEY 2” is received, recognizes the data transfer or not with this value, and generates the bus key

encoded the data. (2) Encoded “Disc Key” and “Title Key” host is transfer with the bus Key. (3) DVD player of host reads the key value, and uses the value to restore the scrambled data.

* Refer to the next page for the details.

Page 43

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. (At this time, the disc key and title key are stored in a disc.) …As above, the disc is able to copy when the disc key and title key are opened. Then, ROM-DRIVE encodes the disc key and title key and transfers to MPEG2 board.

If you want to play the disc prevented from the copy......

First of all, ROM-DRIVE and MPEG-2 board identify with each other through the procedure as described below.

1. Drive and host gives and takes the ID of 2bit. This ID is AGID (Authentication Grant ID). The various decoder boards are attached to the host, in these, AGID sets the MPEG-2 board and drive.

2. After the AGID is set, MPEG-2 board generates the challenge key (10 Byte) and transfers to drive. The board and drive generate key 1 (5Byte) with the challenge key respectively. (Of course, the Algorithm generating the key 1 is not known.)

3. Compare with the generated key 1, if it corresponds each other, the first step of authentication is completed. This is a course to identify the MPEG-2 board with a drive.

4. The second step of authentication is a course to identify a drive with the MPEG-2 board. The dirve generates a challenge key and transfers it to the MPEG-2 board. The dirve and MPEG-2 board generate the key 2 (5Byte) with the challenge key, compare with each other, and if it corresponds and the secondary step of authentication is completed.

5. As above, the identification is completed.

6. The dirve and MPEG-2 board generate the Bus key with the key 1 and key 2 and own it.

7. Dirve encodes the disc key and title key with this Bus key and transfers to the MPEG-2 board.

8. The MPEG-2 board reads the encoded disc key and title key with the Bus key only.

9. MPEG-2 board lets data read from the drive to decode with the read disc key and title key and makes into the video signal by decoding.
