1.1.4 Adaptability
(1) Wide operating environment
An LSI circuits reduce power consumption to 4.9 W (read/write). This drive features a wide
operating environment (drive envronment 5 to 45°C or larger than general office environment).
Dust particles are class 5 millions or less.
(2) Low noise and low vibration
This drive operates quietly (26 dBA or less) even during seek operations and will not degrade the
office environment. Rubber vibration isolators support the drive and minimize vibration.
(3) Vibration resistance (shock resistance)
Rubber vibration isolators protect the drive against external shock or vibration.
(4) Safety standards
• UL1950 (U.S.A., safety)
• CDRH class 1 (U.S.A., laser)
• CSA C22.2 No. 950 (Canada, safety)
• EN60950 (Europe, safety)
• EN60825 Class 1 (Europe, laser)
(5) Various radio wave standards
This optical disk device is installed in a host system, and meets the following standards:
• EN55022 class B, EN50082-1 (European wave standards)
• AS/NZS3548 class B (Australian wave standards)
1.1.5 Interface
(1) SCSI-2
This drive supports the basic SCSI-2 specifications.
SCSI commands enable operation using logical block addresses that are independent of the
physical attributes of the drive, enabling software flexibility in terms of system expansion.
(2) Continuous block processing
Logical block addresses are used for data block addressing. Without consideration of the
physical attributes of track boundaries, the initiator can access data by specifying a block number
in logically continuous data space.
