(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: 

EN55022 class B, EN55024 (European EMC standard) 

AS/NZS3548 class B (Australian EMC standard) 

CNS13438 class B (Taiwanese EMC standard) 

(1)  Conformation to SCSI-2 

The optical disk drives conform to the basic specifications of SCSI-2. 

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)  High-capacity data buffer 

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 input-output processing effectively by using the data transfer capability of 
the SCSI bus irrespective of the effective data transfer rate of the optical disk 
drive.
