摘要:
A testing method capable of quantifying abrasion resistance on the translucent base surface of a high-recording-density optical information medium simply and in a form of reflecting an actual application environment, and judging criteria appropriate for the testing method. When an evaluation test in terms of abrasion resistance on a laser beam incident-side surface is conducted on an optical information medium to and/or from which recording and/or reproducing is made by a laser beam shone into an information recording layer from a translucent base side, and which has the focused radius R, of a recording/reproducing laser beam on the translucent base surface, of 40-400 μm, defined by the following expression (1) R=2T tan [sin−1 (NA/n)](1) (in the expression, T is the thickness (μm) of the translucent base, NA numerical aperture of an object lens in the recording/reproducing device, and n refractive index of the translucent base), the abrasion resistance on a laser beam incident-side surface is evaluated based on the error amount of a reproduction signal after a laser beam incident-side surface is abraded by an abrasion wheel specified in ISO9352.

摘要:
The present invention relates to a method for processing a photoresist-coated board, a method for manufacturing a stamper for a recording medium and a method for manufacturing a recording medium which can form a fine raised and depressed pattern having a uniform width after development even in the case where a laser beam having a relatively long wavelength is used for forming pre-pits on a recording medium with high accuracy. A photoresist-coated board 108 is constituted by laminating a light absorption layer 108b and a photosensitive material layer 108c on a glass substrate 108a in this order and is exposed to a laser beam 102 by condensing the laser beam 102 onto the photosensitive material layer 108c, thereby forming a raised and depressed pattern corresponding to pre-pits on the the photosensitive material layer 108. When the length of a pre-pit to be formed is shorter than 4 T, for example, the duty ratio of the pulse signal train input to the light modulator 109 is varied within a range from about 50% to 65% so that a pulse signal train having a higher duty ratio is generated as the length of a pre-pit to be formed becomes longer and the power of a laser beam is modulated by the thus generated pulse signal train. On the other hand, when the length of a pre-pit to be formed is equal to or longer than 4 T, for example, a pulse signal train having a constant duty ratio is generated independently of the length of the pre-pit to be formed and the power of a laser beam is modulated by the thus generated pulse signal train.

A multilayer optical recording medium is provided with a totally reflective first information layer provided on a substrate and a second information layer being a translucent information layer provided via a spacer layer. The second information layer is composed of a TiO2 layer, a first dielectric layer, a reflective film, a second dielectric layer, a recording film, and a third dielectric layer, all of which are laminated together in this order. The first dielectric layer is made of ZrO2, Cr2O3, and Al2O3, and has a refractive index in the range of 1.84 to 2.20. If the recoding film is made of a material containing Sb as a main component, it is possible to strike a balance between high values of both the transmittance and the degree of modulation in recording information by laser light with a wavelength of 405 nm using an optical recording system having an optical system with a numerical aperture NA=0.85.

摘要:
It is an object of the present invention to provide an information recording method for recording information in a data rewritable type optical recording medium having a plurality of information recording layers whereby a sufficiently high erasing efficiency can be ensured when data recorded in any one of the information recording layers are directly overwritten. In the information recording method according to the present invention, information is recorded in an optical recording medium 10 having at least a stacked L0 layer 20 and L1 layer 30 by projecting a laser beam thereonto via a light incidence plane 13a. In the case where information is to be recorded in the optical recording medium 10, information is recorded in the L0 layer 20 using an off-pulse recording format and information is recorded in the L1 layer 30 using an on-pulse recording format. As a result, even in the case of directly overwriting data recorded in either of the L0 layer 20 or the L1 layer 30, a sufficiently high erasing efficiency can be ensured.
