摘要： Methods are disclosed for manufacturing multi-layer film reflection mirrors, in which a desirable shape accuracy of a reflected wavefront can be obtained after locally scraping the multi-layer film. In an exemplary method, a multi-layer film (comprising respective alternating layers of at least two types of substances having different respective refractive indices) is superposedly formed on the surface of a mirror substrate. The multi-layer film has a constant period length, and the multi-layer film on the substrate is locally scraped to correct a phase of a reflected wavefront from the reflective surface of the mirror. The multi-layer film has an internal stress of 50 MPa or smaller. Alternatively or in addition, a compensating adjustment in a film formed on a reverse surface of the substrate can be made to cancel the stress perturbation caused by scraping of the multi-layer film on the obverse surface of the substrate.

摘要： 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.
