General Description
1-4 C156-E227-01EN
(3) Safety standards
The optical disk drive is certified under the following standards:
• UL1950 (U.S. safety standard)
• CDRH (U.S. laser standard) (Class 1)
• CSA C22.2 No. 950 (Canada safety standard)
• EN60950 (European safety standard)
• EN60825-1 (European laser standard) (Class 1)
(4) Radio wave standards
This optical disk device, while installed, is certified under the following
standards:

−
AS/NZS3548 class B (Australian EMC standard)
−
CNS13438 class B (Taiwanese EMC standard)
1.1.5 Interface
(1) Conformation to ATA/ATAPI-5
The optical disk drives conform to the basic specifications of ATA/ATAPI-5.
ATAPI 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.
In the optical disk drives, PIO mode 4, multiword DMA mode 2, and Ultra-DMA
mode 2 are supported.
(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) High-capacity data buffer
This drive has a 1,844-KB data buffer. This data buffer is used to transfer data
between the EIDE bus and a disk. Since data is stored in this buffer, the host can
execute input-output processing effectively by using the data transfer capability of
the EIDE bus irrespective of the effective data transfer rate of the optical disk
drive.
