ABSTRACT:
In order to improve quality of recording/reproducing signals by preventing degradation of the quality of the recording/reproducing signals due to vibration transmitted from the exterior of a disk cartridge which contains a discoid medium, the disk cartridge performs the following: reference pins are inserted into reference pin insertion entrances and located on the lower side of a housing. These reference pins press the housing onto a reference plate, and the disk cartridge is placed in a recording/reproducing device. Vibration damping members are provided at portions in contact with the reference pins. These vibration damping members are rendered to absorb the vibration transmitted from the exterior of the cartridge through the reference pins. By preventing the discoid media from vibrating in the vicinity of an opening portion, the quality of the recording/reproducing signals are improved.
