(2) Low noise and low vibration
This drive operates quietly 26 dB or less (A character) even during seek operations and will not
degrade the office environment. Rubber vibration isolators support the drive and minimize
vibration. (Low noise and low vibration features are available except while an MO cartridge is
being ejected.)
(3) Vibration resistance (shock resistance)
Rubber vibration isolators protect the drive against external shock or vibration.

! 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, EN55024 (European wave standards)
! AS/NZS3548 class B (Australian wave standards)
! CNS13438 (Taiwanese radio interference standard, except MCE3023AP)
1.1.5 Interface
(1) ATA/ATAPI-4
This drive supports the basic ATA/ATAPI-4 specifications.
ATAPI 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.
Supports PIO Mode 4 and Multi-word DMA Mode 2.
(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.
