の障害が発生する問題を有していた。 When the disk cartridge 2 is inserted and recording is being played back, dust is prevented from entering the housing 1 as described above, but when the disk cartridge 2 is inserted or removed, the door 1A is opened. When the disk cartridge 2 is removed from the spindle 5A, the lid 2E closes the opening of the disk cartridge 2, so that the disk cartridge 2 is sealed to prevent outside air from entering. However, the head portion 4 from which the disk cartridge 2 has been removed is exposed. Therefore, it has the disadvantage that dust adheres to the magnetic head 6 and the like. As described above, if dust adheres to the head section 4 when the disk cartridge 2 is attached or removed, there is a problem in that the playback output decreases during recording and playback and a head crash occurs.
