PURPOSE:To reproduce and record lots of information by scanning a laser light with a prescribed tilt angle with respect to tape running direction so as to apply recording/reproduction. CONSTITUTION:A tracking group 2 is formed with a tile angle theta with respect to the tape running direction 3. Thus, e.g., one group 2 is subject to tracking and one frame of a picture is recorded and reproduction. In forming a group on a transparent polyester tape 5 and a protection film 7 on the film 6 are formed in order to form the optical information recording tape. The recording/ reproduction of the tape is executed by radiating a laser light from the tape 5. An information signal is recorded with high density by the tape and since a large area of the tape is used, lots of information is recorded and reproduced. |
