Abstract
A disc cartridge for rotatably accommodating an information carrier disc, which includes a first casing having a first cavity defined therein for accommodating a portion of the information carrier disc, and a second casing having a second cavity defined therein for accommodating a remaining portion of the information carrier disc and operatively coupled with the first casing for movement relative to the first casing between extended and retracted positions to bring the disc cartridge into opened and closed positions, respectively. Springs are provided for urging the second casing to the first position. When the second casing is moved against the springs, the disc cartridge is brought to the opened position, allowing one or more access openings to be exposed to the outside of the disc cartridge. A disc retainer is also provided for avoiding any arbitrary motion of the information carrier disc within a disc chamber defined by the first and second cavities in the first and second casings.
