CD-ROM Controls and Features

You can plug mini-headphones with a 3.5-mm diameter
miniature stereo plug into this jack.
Use the volume control to adjust the audio output volume to
the headset jack.
The Busy Indicator lights during a data access operation and
blinks during a data transfer. The indicator blinks initially
and then stays lit when there is one of the following:
• A defective disc
• A disc insertion error (for example, an upside-down disc)
• No disc present
Press the Eject Button to open the Disc Tray and insert or
remove a disc. When the drive is in use, you must press the
eject button for more than one second to open the Disc Tray.
By removing the Phillips type screw and inserting the end of
a paper clip, you can open the Disc Tray when the
workstation does not have power.
The Volume Control, Headset Jack, and Audio Jack features of the CD-ROM
drive are supported through applications only.

CD-ROM Media

CD-ROM discs are 120 mm (4.7 in.) in diameter, and use one data surface
with a capacity of approximately 600 megabytes. The data surface contains
pits and flat spots arranged in a continuous spiral track, which is read at a
constant speed. You may access files and data stored on a CD-ROM disc, but
you may not write files or data to a CD-ROM disc.
CD-ROM data discs are identical to audio compact discs (CDs) except that
they store computer data and information.
