Product Information
This chapter provides general product information and lists important features and speci-
fications. A matrix of environment specifications provide parameters for several sub-
assemblies.

Product Features
The SCSI-connect version of the RW551, RW552 optical disk jukeboxes have
the following features:
• direct online access to data
• data security through the ability to "lock" the jukebox, preventing disk re-
moval

Medium Optical Disk (RW551/RW552) Library

• SCSI Interface
• single-ended or differential
• SCSI-2 command set
• autochanger reliability of:
• 100,000 hours MTBF (Mean Time Between Failure)
• 1,000,000 MSBF (Mean Swaps Between Failure)
• modular replacement of all major assemblies
• downloadable firmware for the drive mechanism and the autochanger con-
troller PCA
• a digital signal processor (DSP) based servo built into the drive mechanism for
faster seek times and lower error rates
• split optics resulting in the use of a lighter optical head for faster and more ac-
curate data access
• full read and write data caching to optimize system performance
• high reliability and data security when using DEC brand rewritable and write-
once 5.25-inch optical disks
• Digital magneto-optical disks meet the following standards:

The Optical Drive Mechanism
The optical drive mechanisms (RWZ53) in the autochanger of the jukebox are
multifunction drives that can operate in both rewritable and write-once modes.
The drives use both rewritable and write-once 5.25-inch magneto-optical disks
that comply with ANSI and ISO standards for Continuous Composite format.
The drives can sense a rewritable or write-once disk by the formatting on the
disk and enter the appropriate mode.
