摘要： A radiation-sensitive carrier body directly utilized as a stamper has a glass substrate, a first highly adhesive layer securely adhered to the substrate, a radiation-sensitive layer which discharges a gas component upon being irradiated with a laser beam and which locally forms a protuberance due to the absorbed energy, a second highly adhesive layer securely adhered to the specific material of the radiation-sensitive layer and which deforms in accordance with deformation of the layer, and a metal layer which has a high releasability to allow easy separation from a optical disk substrate material such as an acrylic material when the carrier body is used as a stamper substrate for manufacturing optical disks. A protuberance formed on the carrier body such as a continuous spiral protuberance allows formation of a corresponding spiral groove in the acrylic material, serving as a pre-track into which desired information will be digitally written by a user.

摘要： An optical information recording medium is produced by introducing a plasma-generation gas comprising hydrocarbon into a plasma-generating region provided with a metal target and a substrate. The pressure of the plasma-generating gas is maintained within a predetermined range within the plasma-generating region. Electrical power is applied to the plasma-generating gas to dissociate the gas thereby forming a plasma. The generated plasma sputters the metal target, thereby allowing the sputtered metal to be deposited on the substrate in the form of a film containing the metal and the carbon liberated from the hydrocarbon. During sputtering, the product between the density of the power applied to the electrode and the average residence time of the plasma-generating gas within the plasma-generating region is controlled within such that the product falls within the range of more than 0.5 W-sec/cm.sup.2 and less than 50 W-sec/cm.sup.2, and the partial pressure of a secondary hydrocarbon, which is different from the introduced hydrocarbon, present during the dissociation to the secondary hydrocarbon before the dissociation and after the introduction is set to range between 2 and 12.

摘要： There is disclosed a method for manufacturing a bubble-mode optical disk having a recording layer made of a mixture of an indium oxide matrix containing indium clusters and organic clusters. The indium clusters absorb an energy of incident laser beam to heat the organic clusters which then release a gas component such that the matrix is locally deformed to form a protuberance. A plasma sputtering is used to deposit the recording layer on a disk substrate placed in a sputtering chamber. A target body used is made of indium. A low-pressure gaseous atmosphere in the chamber includes a methane series hydrocarbon gas and an oxygen gas. The gaseous atmosphere may include a hydrogen gas or a nitrogen gas.

摘要： In an optical disk, a single recording layer is formed on a transparent substrate. The recording layer has an insulative base layer in which metal clusters and organic clusters are uniformly contained. When radiation is incident on the recording layer such that the intensity of the radiation is changed in accordance with the type of recording information, the metal clusters absorb radiation energy. The organic clusters produce a gas component in accordance with a level of the radiation energy absorbed by the metal clusters, thereby causing the base layer to incur a local projection by a pressure of the gas component such that a protuberance is formed on the base layer.
