摘要:
An information storage medium consists of a polycarbonate substrate and a recording layer formed on the substrate and containing an AgTe eutectic alloy, carbon, and hydrogen. Information is recorded on the medium by forming pits in the recording layer upon radiation of a laser beam, and is reproduced by radiating a reproducing laser beam onto the recording layer in which the pits are formed and detecting reflectances.
摘要:
An information storage medium comprises a substrate and a recording layer formed on the substrate containing Te, Ge, C and H. The recording layer is formed by sputtering, with a Ge-Te alloy being used as a target and with a mixed gas of a noble gas and a hydrocarbon being used as a sputtering gas. The hydrocarbon content in the sputtering gas falls within a range of 3 to 35%. The composition of the target is Ge.sub.x Te.sub.100-x (where x is expressed by atomic %, and 5.ltoreq.x.ltoreq.20).
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.

A composite magnetic head includes a recording head and a reproducing head. The recording head may be formed below or above the reproducing head. The lower of the recording and reproducing heads includes a first electrode. In addition, a conductive layer acting as a pole structure for the recording head includes a portion defining a hole through which a second electrode is made to contact the first electrode.
摘要:
A system for communicating through a public telephone network includes a terminal side adapter which connects either a telephone set or a non-telephone terminal (such as a gas meter terminal) to the telephone network. Communication with the non-telephone is normally scheduled during the early morning hours to minimize conflict with normal telephone usage. Communication with the non-telephone terminal is initiated from a data center. A center side adapter unit makes a predetermined sequence of calls during predetermined time zones, and each of these calls is quickly interrupted without being answered at the terminal side. However the sequence of interrupted calls signals the terminal side adapter unit to telephone the data center and to connect the non-telephone terminal to the telephone network. If the terminal side adapter unit receives an incoming call outside the time zones, or if a call received within a time zone is not quickly interrupted, the incoming call is routed to the telephone set.
摘要:
An optical recording medium and methods of manufacturing the same are disclosed. The optical recording medium is provided with a transparent adhesive layer containing organic compounds such as hydrocarbon or the like that constitute resin materials, and metallic compounds whose thermal expansion coefficients are nearly equal to those of inorganic transparent materials that constitute a transparent protective layer, whereby peel-off phenomena to be caused by secular variation can be avoided.
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.
