Reliability; Maintainability/Operability; Adaptability - Fujitsu MCM3064SS Product Manual

1.1.2 Reliability

(1) Mean time between failures (MTBF)
The mean time between failures (MTBF) for this optical disk drive is 120,000
hours or more.
(2) Enhanced error recovery
If an error occurs on the optical disk drive, the system executes appropriate retry
processing to recover from it. This drive features enhanced Reed-Solomon error
correction code (ECC) to assure error-free operation.
(3) Automatic allocation of alternate data blocks
This drive features a function which automatically allocates alternate data blocks
in cases where defective data blocks are detected while data is being written to an
optical disk.

1.1.3 Maintainability/operability

(1) Diagnostics function
This drive has a diagnostics function for checking optical disk drive operations.
The diagnostics function facilitates test and restoration.
(2) Five-year service life (no overhaul)
This drive will not require overhaul within the first five years of installation if
appropriately maintained (both disks and optical parts cleaned using cleaning
tools) and handled as recommended.

1.1.4 Adaptability

(1) Wide-ranging operating environments
This drive, requiring low power consumption because of LSIs adopted, can be
used in wide-ranging environments (5 to 45°C for drive's ambient environment
and a general office environment). The ambient cleanliness must be class 5
million or less particle level.
(2) Low noise
This drive operates quietly at 30 dB or less (A-character) during seek operations
and will not degrade the office environment (except when an optical disk is
ejected).
