Abstract

Abstract The fist means has a tray for mounting a recording and reproducing medium at a first position directly or through an auxiliary part, and coupling the turntable which is rotated by a disk driving motor of the main chassis with the driven part of the recording and reproducing medium at a second position, and this tray is designed to mount both a recording disk alone and a recording disk contained in a disk cartridge, while the second means couples the disk alone to the turntable at a first position of the main chassis, or puts the cartridge into the cartridge retaining means at the first position of the main chassis, and couples the recording disk in the cartridge to the turntable while reaching a second position of the main chassis, thereby recording and reproducing at the second position of the main chassis, and therefore the both means are commonly constituted to record and reproduce at the same position in both recording disk alone and the recording disk in the cartridge, so that both the recording disk alone and cartridge can be used by one apparatus. In the third means, in addition to the constitution of the first means, the holder moving up and down obliquely in the tray mounts plural types of disks concentrically, with ones larger in diameter at higher positions, at an obliquely lowered position, and the smaller cartridge of the plural types of cartridges is arranged concentrically with the disk alone, while the larger cartridge is deviated in the center in the moving direction of the tray, being put on higher positions, and when the tray moves to the recording and reproducing position and is coupled with the turntable, the holder is raised obliquely except for large cartridge, and all recording disks alone and recording disks in cartridge are at the same position, so that all media can be handled in one apparatus.
