1.1.5 Interface
(1) Conformation to
The optical disk drives conform to the basic specifications of
SCSI commands specify data with logical block addresses, thus allowing data to be manipulated independent of the physical characteristics of the optical disk derives. This facilitates easy development of software whose functions can be flexibly expanded in the future.
(2) Continuous block processing
Logical block addresses are used for data block addressing. Irrespective of the physical attributes of track boundaries, you can have the initiator access data by specifying a block number in logically continuous data space.
(3)
This drive has a 2 MB data buffer. This data buffer is used to transfer data between the SCSI bus and a disk. Since data is stored in this buffer, the host can execute
