The RelAdr bit is not supported and must be set to zero.

If the drive received a WRITE (10) or a WRITE (12) Command which causes an ov r run co dition of the writing buffer, the execution of the command is deferred until the blank area of the buffer grows to be able to r c ive whole the data specified in the command. In this period, the interface bus is held by the drive.

A recording start is carried out when one of the following co ditio s is real zed. 1)Write Buffer fills.

2) SYNC CACHE command is received.

C IONEERIn the recording state ,if a buffer-under- un occurs, the drive leaves data for 1ECC and interrupts record operation temporarily

In the recording state ,if eject or read request ccurs, the data in a buffer is recorded and it ends. Eject or read request is

performed continuously.

until It receive the following W ite command.

The Streaming bit of the WRITE (12) Command is reflected to the time-out value of write starting. If Streaming bit is set to one, the time-out value is s t to 2 s c. If St eaming bit is set to zero time-out value is set to 5 sec. The drive maintains the Streaming bit of the latest Write (12) Command and determines the time-out value by maintained Streaming bit when writing operation is started. If sequ tial data are transferred, the Streaming bit of all WRITE (12) Command needs to keep same value.

The time- ut value is valid in normal operating condition. If the drive is in abnormal condition, for example play backing the damaged area on the media, the time-out value will be grower by the drive to return from emergency condition of servo

Pmechanism.

The FUA bit and the TSR bit are not supported and these are ignored.

For BD-RE/R, if the Streamig bit is set to one, Stream recording operation is used.

The VNR bit of WRITE(12) is applicable to BD-RE/R.

4.23 WRITE BUFFER Command

This command is used for checking the drive or firmware update.

The specifications of this command are vendor unique.
