TOSHIBA DVD-RAM SD-W1111 ‘99/06/26 Version 1.0
Matters to be attended to:
This drive adopts RPC-II for its “Standard Specification Model”.
This DVD-RAM Drive adopts RPC-II, the Phase II System of RPC (Regional Playback Control) for “Standard Specification Model”, on the basis of a contract with the CSS (Contents Scramble System) organization. (all of our former DVD-RAM Drives adopted RPC-I, the Phase I System.)
The CSS rule requires that all the products not only DVD-RAM Drives but also PC systems installing DVD-RAM Drives sold from Jan.1, 2000 need to support RPC-II described above.
To playback a DVD-Movie Software with the Regional Code specified by using a DVD-RAM Drive with RPC-II adopted, either the hardware or software used as applications on PC system side is also required to meet RPC-II.
Namely, in the status that a hardware or a software for a DVD-Movie Playback Application planned to use in a PC does not support RPC-II, if the "RPC-II (Standard Specification) Drive" is used in combination, DVD-Movie Softwares with the Regional Code specified (most of DVD-Movie Softwares currently available on the market) cannot be reproduced. So, in such a case, "RPC-I Specifications Supported Model" must be purchased for a while.
However, all the drive manufacturers must obey to the deadline specified by the CSS rule saying; all DVD-RAM Drives have to implement Phase II from Jan.1, 2000. So we recommend that you will change your DVD-Movie Playback Hardware or Software to those applicable to the PRC-II as soon as possible and investigate to combine your system with the RPC-II Specification Drives.
Since we determine the drives are of RPC-I or RPC-II when manufacturing at factory and ship, the specification change after shipping is not available in principle. Especially, changing the RPC-II specification drive to the RPC­I is prohibited by the CSS rule.
In the combination of the drive and PC system with RPC-II supported, as far as the Regional Code of a DVD-Movie Software and the code memorized in the RPC-II Specification Drive coincides, the Movie Software is allowed to carry out.
In the RPC-II Specification Drive, the region change by an end user is permitted up to 5 times in total including the initial region set. After change to the fifth region is carried out, the Drive enters Parm State (“no change allowed” status).
The drive with Parm State is permitted up to 4 times of "reinitialization" by a drive manufacturer or a specific service center authorized by the CSS. Since it is considered that the reinitialization is carried out after the completion of the region confirmation through test items in the PC manufacturer’s manufacturing line or the completion of drive repair, etc., the number of reinitialization times may vary from 0 (no reinitialization available) to 4 times. So, we recommend that not to disclose the reinitialization process to end users but only to inform the number of region setting times as "end user’s direct region setting is available up to 5 times in total."

*Notes 1) the low level of all signals returns TRUE. Use Hirose Electronics Co. HIF 3BB-50DA-2.54R, Molex 5320-50AT2 or equivalent one for the connector on cable side. The voltage is added on the TERMPWER signal from the internal side of a drive. The maximum power supply current from internal side of a drive is 1.1A. If the current exceeds this level, the internal current limiter operates to stop the voltage addition. After the cause of excess current is removed, the signal returns to the original status.

14. Notes on data guarantee
14.1 Disappearance of data in buffer in a write cache operation
In a write cache operation, before data are actually written to a disc, a status response to the WRITE command or WRITE & VERIFY command is sent. If the power supply is switched off immediately after the status response, there is a possibility that the data in the buffer will disappear before being written to the disc. To avoid this problem, execute FLUSH CACHE command before switching off the power supply. Always execute FLUSH CACHE command before switching off the power supply, to avoid any risk of disappearance of data in buffer.
14.2 Error report in a write cache operation
When an error which cannot be recovered before all the data is received and written in the buffer and a status response to the command is sent in the write cache operation, the error is reported as 71H in REQUEST SENSE DATA. This shows that the error occurred on the last WRITE command or WRITE & VERIFY command.
14.3 Automatic sector replacement at a write operation
When data can not be written to the disc normally due an unrecoverable error, such as ID NOT FOUND, the drive replaces the sector by sector replacement processing. The drive prevents data from being lost by this operation as much as possible. Because automatic sector replacement processing is executed after write retry ends in an error, a time of between 7 to 15 seconds is needed. Therefore, it is recommended that the time-out to the command generating access to the disc is set at 20 seconds or more. In a write cache operation, when automatic sector replacement processing is done after a status response to the command is send, execution of the following command can be made to wait. However, when the following command is a WRITE command or WRITE & VERIFY command, the first data transfer of one block is executed without waiting, to prevent a time-out of the host.
14.4 Verification of a block address
When the command is received, a drive calculates block addresses where the data are written or read, with the start address and length specified by the command, and verifies whether the block addresses contain a block address which does not exist. If such a block address exists is founded, the drive does not record nor read, and reports on the error to the command at once.
14.5 Error generation in Read Modify Write operation
If, in a WRITE command and WRITE &VERIFY command, a start address number is not other than *****0H or a block length is other than *16 x (integer)* though the start address number is *****0H, the drive reads all data in an ECC block which contain the specified address once, and replaces the data in the ECC block by the data of the specified address. This chain of operations is called "Read Modify Write Operation". In "Read Modify Write Operation", in WRITE command and WRITE&VERIFY command, an error occurs when the data of the ECC block cannot be read for some reasons.

Moreover, not only the data which tried to be recorded but also the data of other addresses in the same ECC block might be lost due to the failure to record.

15. MISCELLANEOUS
15.1 Accessories
Function setting jumper pins 5 pieces. Emergency eject tool 1 piece.
15.2 A bare disc setting at vertical installation
In case of using a bare disc (ex. DVD-ROM or CD-ROM) at vertical installation, use disc holders on the tray. Please read the following explanations thoroughly at this time.
1. Draw three disc holders among the four holders on the tray, two pieces are both holders in down side, one piece is on a rear part in upper side while made to vertical posture as follows.
(Note) Please use 3 pieces holders because the set of the disc becomes difficult when four disc
holders are drawn out.
2. Drawing out a disc holder (pull return) can be easily done with inserting a propelling pencil ahead in the hole that is installed on the disc holder.

3. First hang a disc on a disc holder in an upper and rear side of a tray, and then put the disc on disc
holders in a down side of the tray.
4. Check three disc holders to confirm to the disc surely.

Notes in use
(1) A disc might be scratched, damaged and dropped from a tray when used with a disc not correctly
installed. Please install correctly and use a disc. (2) Please do drawing out (pulling return) a disc holder before setting a disc in a tray. (3) Please do drawing out (pulling return) a disc holder with the power supply not supplied to the
drive as much as possible, because the auto-loading function might work and the tray might enter the drive during drawing out or pulling return the disc holder. When doing with the power supply to the drive unavoidably, work carefully holding the tray by
hand firmly. (4) When using a drive by vertical posture, 80 mm DVD/CD cannot be used. (5) When DVD-RAM (cartridge type) is used, the position of a disc holder need not be returned.

15.3 Disc eject at emergency
Please do according to the following procedures when it is necessary to take out a disc from the drive in the emergency. Check that the power supply of the drive is turned off and one minute or more passes. Insert an attached emergency eject tool in the emergency eject hole and push bumping inside. (Figure
1) Front bezel opens a little and an inside tray rises. (Figure 2) When the tray comes out forward, draws out it and the disc is taken out. (Figure 3) Please draw out the tray with an emergency eject tool, when the tray does not come out. (Figure 4)
