Abstract
A disk file apparatus including a transfer member disposed at the upper side of a shelf for accommodating a multiplicity of cartridges each receiving a disk both sides of which are able to be subjected to recording and reproducing, each cartridge having a forward extending groove formed in the rear portion thereof. The transfer member has lever means which is arranged such that, when a cartridge having the same rating as that of said cartridges is inserted into the transfer member, the lever means detects whether or not there is a groove which is formed in the rear portion of the cartridge. The apparatus further includes a controller which is arranged such that, when the lever means detects the groove formed in the rear portion of the cartridge inserted in the transfer member, the controller activates a carrier to turn the cartridge through 180 degrees while the cartridge is being moved from the transfer member to an empty accommodating space in the accommodating shelf, and when the downward side of the disk received in the selected cartridge is not coincident with the side which is to be subjected to writing or reading of information in the coder, the controller activates the carrier to turn the selected cartridge through 180 degrees before it is loaded into the coder. Accordingly, all the cartridges accommodated in the accommodating spaces have the disks facing downward. Thus, the judgement as to which side of the disk in a selected cartridge faces downward need not be made between the selection of the cartridge and the loading of the selected cartridge into the coder, and therefore it is possible to shorten the access time.
