MOLD FOR TAPE-SHAPED OPTICAL RECORDING MEDIUM, TAPE-SHAPED OPTICAL RECORDING MEDIUM, AND CUTTING DEVICE THEREFOR
There is provided a mold for a tape-shaped optical recording medium with which precise cutting can be performed along a cutting guide groove, the mold forming a recording groove in a tape-shaped optical recording medium, and having a plurality of recording and reproduction bumps that form a recording and reproduction groove, and a guide whose shape is different from that of the recording and reproduction bumps.
1 . A mold for a tape-shaped optical recording medium, which forms recording and reproduction grooves in a recording medium, the mold comprising:
a plurality of recording and reproduction bumps that form the recording and reproduction grooves; and
a guide whose shape is different from that of the recording and reproduction bumps.
2 . The mold for a tape-shaped optical recording medium according to claim 1 ,
wherein the guide has a convex portion or a concave portion.
3 . The mold for a tape-shaped optical recording medium according to claim 1 ,
wherein the guide is provided at both ends in the width direction so as to sandwich the plurality of recording and reproduction bumps.
4 . The mold for a tape-shaped optical recording medium according to claim 1 ,
wherein a plurality of the guides are provided, and
the plurality of guides are equally spaced.
5 . The mold for a tape-shaped optical recording medium according to claim 1 ,
wherein the guide is provided to a first end in the width direction.
6 . A tape-shaped optical recording medium prior to be cut to finished size by a cutting device, the tape-shaped optical recording medium having:
a plurality of recording and reproduction grooves; and
a guide whose optical reflectivity is different from that of the recording and reproduction grooves.
7 . The tape-shaped optical recording medium according to claim 6 ,
wherein the guide has a shape that is different from that of the recording and reproduction grooves.
8 . The tape-shaped optical recording medium according to claim 6 ,
wherein the guide has a convex portion or a concave portion.
9 . The tape-shaped optical recording medium according to claim 6 ,
wherein a plurality of the guides are provided.
10 . A cutting device for cutting the tape-shaped optical recording medium according to claim 6 , comprising:
a detector that detects a position of the guide; and
a cutter that cuts the tape-shaped optical recording medium along the guide.
11 . The cutting device according to claim 10 ,
further comprising an actuator that moves the tape-shaped optical recording medium, which has been cut by the cutting device, in the width direction on the basis of the detection result of the detector.
