Abstract

PURPOSE:To attain the effective use of a recording medium by forming the control areas and the data areas alternately on the recording medium and recording the control data into a control area together with the address of the next control area. CONSTITUTION:A basic control area 1 of a certain extent is prepared at the head of a magnetic tape 10. Then data are recorded in the area 1 and then the control data including the file names, the attribute area addresses are recorded in the area 1 in relation to the data recorded first. This data recorded area is defined as a data area 1D. When the area 1 is filled with the control data, a control area 2 of a certain extent is added after the area 1D. At the same time, the head address of the area 2 is recorded in the area 1. Hereafter the new control areas are added every time the preceding area is filled with the control data. As a result, no useless control area exists and the data on the recording medium can be totally controlled. Then the recording medium is effectively used.

[Problems to be Solved by the Invention] By the way, in such a recording format, even if data attributes are increased or data management is subdivided, it is possible to manage data on the entire magnetic tape 10. In order to do this, it is necessary to reserve a sufficient amount of management area 20.

[Function] In the above configuration, a basic management area 1 to some extent is first provided at the beginning of the recording medium, and then a new management area 2, 3, . . . , N is created every time it becomes full of management data. will be established. Therefore, data on the entire recording medium can be managed without having a wasteful management area, and the recording medium can be used effectively.

In this example, the recording format on the magnetic tape 10 is as shown in FIG. That is, first, a certain amount of basic management area 1 is provided at the beginning of the magnetic tape 10. Then, data is recorded next to this management area 1, and in relation to this data, the file name,
Management data such as attribute area addresses can be recorded. The data recording area at this time becomes the data area ID.
