Abstract
Disclosed herein is an optical storage device including an optical head having an objective lens for focusing a light beam from a light source onto an optical recording medium accommodated in a cartridge shell, and a photodetector for detecting a regenerative signal from reflected light from the optical recording medium. The optical storage device further includes a cartridge holder having a main surface for holding a cartridge inserted in the optical storage device. First and second cartridge holding assemblies are mounted on the main surface of the cartridge holder in the vicinity of a first side thereof in such a manner as to be spaced from each other and to partially project into the cartridge holder. A third cartridge holding assembly is mounted on the main surface of the cartridge holder in the vicinity of a second side thereof opposite to the first side so as to partially project into the cartridge holder. Each cartridge holding assembly includes a cartridge holding member having a flat surface for holding the cartridge shell.
