[Problems to be solved by the device]

 In recent years, external storage devices such as magnetic disks and magneto-optical disks have been increasing in capacity. Therefore, the recorded contents in the recording medium of the external storage device are often modified. In addition, in an OS such as MS-DOS and UNIX, a file system that manages files in a tree structure is adopted, so that it becomes difficult to manage files as the number of directories and files increases. Furthermore, in a removable storage device such as the magnetic disk device described in Japanese Utility Model Laid-Open No. 1-116990, it is impossible to view the contents of the recording medium when the storage device is disconnected from the computer. Since a removable type recording apparatus uses a plurality of cartridges, it is highly likely that the recorded contents in the cartridges will not be understood as the storage capacity increases. In that case, connecting to a computer to search the stored contents of the recording device does not take a short time, and especially when many cartridges are used, it takes a lot of time to attach / detach and retrieve the cartridge. A method of using an index label as described in Japanese Utility Model Laid-Open No. 63-193271 may be considered, but since the directory name or file name is taught by printing or writing, the index label is used even if the file name or directory name is changed. Since the entered contents are not updated in the initial state, they are not suitable for large-capacity external recording devices where the recorded contents are often modified. In the display device described in Japanese Utility Model Laid-Open No. 63-193265, the disk information is displayed, but the file name and directory name are not displayed. Therefore, the external storage device for the computer in which the file name and directory name are updated Not suitable for.

In order to solve this problem, an object of the present invention is to provide the latest directory name stored in the recording medium contained in the cartridge even when the cartridge containing the recorded content is detached from the main body of the recording apparatus. It is possible to check the stored contents such as a file name and a file name, and to easily and quickly search for a desired cartridge or a desired file.
