Disk-cartridge-type adapter

摘要

The head (41) of a disk-cartridge-type adapter has a gap width and a head length that are sufficiently large to cover a setting error between the heads of the adapter and disk cartridge drive (70). The head (41) of the adapter is covered with protective films having grooves. The head of the adapter has reinforcing supports each having a hollow in which the head of the disk cartridge drive moves. The head and supports of the adapter have holes for passing a shaft fixed to the adapter. The diameter of the holes is greater than that of the shaft. The adapter has a write-protect mechanism and a double-density detecting mechanism. The adapter has a card slot provided with a stepped part, and a hole used to extract an IC card from the adapter. The adapter has a unit for sidewardly inserting and extracting a power source into and from the adapter. The adapter has heat radiation holes. Such a disk-cartridge-type adapter is capable of preventing damage to a head of the adapter and a head of a disk cartridge drive into which the adapter is inserted, even if these heads are deviated from each other. The adapter is also capable of effectively using the functions of the disk cartridge drive. <IMAGE> <IMAGE>
