Abstract: There is disclosed a bubble-mode data-rewritable optical disc, which has a transparent substrate and a recording layer, formed on the substrate, for storing data to be optically rewritable. The substrate is at least partially formed of an organic material, which releases a gas component when it is heated at a radiation region of a data recording light beam. The recording layer is deposited on the substrate by co-sputtering or co-vacuum evaporation. The recording layer is made of a specific amorphous material containing silicon and fine metal particles. When the gas component is released from the substrate, the recording layer is deformed to be locally peeled off out of the substrate by pressure of the gas component, thus forming a protuberance. In a data erasing mode, a data erasing light beam is radiated onto the recording layer, which is then deformed so as to cause the protuberance to disappear, and has a substantially flat surface, thereby erasing the stored information.

Abstract: A rewritable information recording medium which has a recording layer containing a Group I transition element and a Group IV representative elements of the Periodic Table as two principal element and a support substrate for physically supporting the recording layer, and an information-write, -read, and erase method using this recording medium. When the recording layer is immediately cooled after it is heated up to near a eutectic temperature of the two principal elements, two metastable phases having different energy levels appear. A state in the first metastable phase of the higher energy level has a reflectivity sufficiently higher than that of a state of a mixed phase including the second metastable phase of the lower energy level, or that of the equilibrium state. The state in the first metastable phase can be obtained by heating a recording layer in another state by light beam irradiation. A portion in the first metastable state is cooled after it is heated to a temperature lower than that for obtaining the first metastable phase, so that it can be converted to a state of the low reflectivity, i.e., a state of a mixed phase including the second metastable phase or to the equilibrium state.

Abstract: 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.

Abstract: 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.
