摘要:
A stamper with a sharp uneven pattern is obtained, and high precision information media can be manufactured using this stamper. A method of manufacturing a stamper comprises the steps of manufacturing a photoresist master 100 by forming a light absorption layer 103 and a photoresist layer 104 on top of a substrate 102, forming a latent image on the photoresist layer 104, and then forming an uneven pattern 106 in the photoresist layer 104 by developing the latent image, forming a Ni thin film 108 on the uneven pattern 106 of the photoresist master 100 by electroless plating, forming a Ni film 110 on top of the Ni thin film 108, and then removing the Ni thin film 108 and the Ni film 110 from the photoresist master 100 to form the stamper 120, wherein as preliminary treatments prior to the step of forming the Ni thin film 108 on the photoresist layer 104, a metal catalyst is provided on the surface of the uneven pattern 106, the metal catalyst is activated, and the surface of the uneven pattern 106 on which the metal catalyst has been provided is washed with ultra pure water.
摘要:
A groove is present in a surface of a disc substrate. A part of the groove is curved toward another groove adjacent to the groove to thereby form a land pre-pit. The following relations hold among DG, DP and r: 0.267≦(DP/DG)2·r≦0.701; and 3.185≦(DP/DG)/r≦8.553, where DG: depth of the groove 4B, DP: depth of the land pre-pit 5A, r [&mgr;m]: distance between the center of the land pre-pit 5A and the center line of the groove 4B having the curved land pre-pit 5A.
摘要:
In an optical recording medium comprising a substrate including parallel extending lands and grooves on one surface thereof, the grooves serving as recording tracks, and the lands being formed with prepits, the height HP of the land disposed between the prepit and the groove divided by the height HL of the land in a prepit-free region, both as measured from the groove bottom, i.e., HP/HL ranges from 0.25 to less than 1. This enables to significantly increase the recording density of the medium without a substantial cost increase.
