Abstract
Provided is a tape recording medium including: a base layer having a first surface and a second surface; a first recording layer disposed over the first surface of the base layer and capable of optically recording first data; an imprinted layer disposed between the base layer and the first recording layer; and a second recording layer. The second recording layer is disposed over the second surface of the base layer, contains a magnetic material, and has recorded second data different from the first data.
Claims7
A tape recording medium comprising:
- a base layer having a first surface and a second surface;
- a first recording layer disposed over the first surface of the base layer and capable of optically recording first data;
- an imprinted layer disposed between the base layer and the first recording layer;
- and
- a second recording layer disposed over the second surface of the base layer, containing a magnetic material, and having recorded second data different from the first data.
An information recording/reproducing device for recording or reproducing first data in or from a tape recording medium, the device comprising:
- an optical recording/reproducing unit configured to optically record or reproduce the first data;
- and
- a magnetic recording/reproducing unit configured to magnetically record or reproduce second data in or from the tape recording medium, the second data being different from the first data.
A method of manufacturing a tape recording medium, the method comprising the steps of:
- forming a base layer having a first surface and a second surface;
- forming a first recording layer disposed over the first surface of the base layer and capable of optically recording first data;
- forming an imprinted layer between the base layer and the first recording layer;
- forming a second recording layer disposed over the second surface of the base layer, the second recording layer containing a magnetic material;
- recording second data different from the first data in the second recording layer, the second data being information relating to a position along a longitudinal direction of the tape recording medium.
