Introduction
1.1 Scope
This manual is for the user and operator of the RRD40 Optical Disc Drive.
The RRD40 is a read-only storage device that reads data stored on removable
optical discs. An optical disc is 4.7 inches in diameter and can store 600
megabytes (about 600 million characters) of data.
In optical storage devices, data (which is stored on the disc) is read off of the
disc by a laser system. A laser is a concentrated beam of light. In the RRD40,
the laser (contained in the RRD40 disc drive) shines light on the disc. The
intensity of the light reflected back (to the laser from the disc) determines the
data on the disc. The concentrated beam of light from the laser is so fine that
it is possible to store massive amounts of data on a single disc.
1.2 Product Variations
There are two RRD40 drives that use one of two interfaces.

1-2 Introduction
1.2.1 Drives
The RRD40 is available as a tabletop version or a "half-height" version. The
half-height version is designed to be embedded into an existing host system
enclosure. Figure 1-1 and Figure 1-2 show the two RRD40 drives. Although
the two are physically different, they are functionally the same.

1.2.2 Interfaces
The RRD40 has two possible interfaces: Q-Bus and SCSI.
An RRD40 with a Q-Bus interface uses the M7552 controller module as the
interface to the host system. The Q-Bus interface is used in only the tabletop
version of the RRD40 drive.
An RRD40 with the SCSI interface uses a SCSI controller module as the
interface to the host system. The SCSI controller connects to the SCSI adapter
in the host system and functions as a SCSI device on the host system. An
RRD40 with the SCSI interface is available for both the Tabletop and Half-
Height RRD40 drives.
