Super-resolution optical recording medium on which information is recorded using train of prepits, optical recording medium reproduction device, and control method
A super-resolution optical recording medium (10) of the present invention includes: a medium information region (1) on which medium identification information is recorded; a content region (3) on which content information is recorded; and a blank region (2) provided between the medium information region (1) and the content region (3) and in which at least two tracks are provided so as to connect a train of prepits in the medium information region (1) and a train of prepits in the content region (3). No information is recorded on the blank region (2). With this arrangement, the present invention provides a super-resolution optical recording medium in which a region on which medium identification information is recorded and a region on which content information is recorded are different in track pitch and in which a reproduction error hardly occurs when reproduction shifts from the region on which the medium identification information is recorded to the region on which the content information is recorded.
