DISK CARTRIDGE

摘要

PURPOSE: A disk cartridge is provided to prevent pollution due to dusts by shielding a path where dusts come into an information area through a gap of an outer peripheral part of a disk. CONSTITUTION: A case(210,220) has an aperture hole(221) for accessing a recording surface of a disk(D1) on one side surface and an open hole(211) formed on the other side. A circular shutter(230) and a rotating shutter(240) are movably installed in the case for opening and closing the aperture hole and support the disk. A disk holder(250) is installed at the open hole of the case for covering a gap between an outer peripheral part of the disk and the shutter. A shutter driving element moves the shutter to open and close the aperture hole. A lifting element lifts the disk holder.
