Disk drive

摘要

A disk drive capable of preventing an incorrectly inserted cartridge from further advancing in the earliest possible stage of insertion and securing the longest possible stroke of automatic transfer of the cartridge. A slider is provided for transferring a disk cartridge that is being inserted between the mounting and dismounting position and a fully inserted position while moving together with the disk cartridge with respect to a holder for guiding and holding the cartridge. The slider is provided with a projection that faces a specified side portion of the disk cartridge extending in the direction in which the cartridge is inserted and allows the insertion of the cartridge while being slidably fitted in a groove provided on the side portion of the disk cartridge extending in the direction in which the cartridge is inserted when the disk cartridge is being inserted in the correct position. The projection prevents the disk cartridge from being advanced further when the cartridge is being inserted in an incorrect direction with the same or correct width of insertion.
