摘要： A thin film magnetic head includes a three-step configuration including deep and shallow groove surfaces, a super shallow groove surface, and an air bearing surface, and also, island-shaped center rail is provided in the center of the air outflow end of the disk-facing air bearing surface having a boundary on the surface of base alumina between a head element portion and a substrate, without including the surface of the substrate. Further, by providing in the surface of the substrate the super shallow groove surface shallower than a shallow groove surface, an alumina recession between the surface of the substrate and the head element portion, produced in a shallow dual step sub ambient slider, can be eliminated. Magnetic spacing between the head of the head element portion and the magnetic layer of the disk can be thereby reduced.

摘要： Different formats, whose defect management methods differ based on the presence or absence of a cartridge, are adopted for information storage media having the same physical characteristics. An information processing apparatus is capable of mounting a storage medium having a data recording area. The data recording area includes a user area to which logical addresses are allocated in accordance with recording units. The information processing apparatus includes: a determination section for, based on physical characteristics of the mounted storage medium, determining which one of a first storage medium accommodated in a cartridge and a second storage medium not accommodated in a cartridge has been mounted; a processor for, based on a result of determination, giving an instruction that, when the second storage medium has been mounted, the data recording area be formed as the user area and a spare area, and giving an instruction that, when the first storage medium has been mounted, all area of the data recording area be formed as the user area; and a recording section for, based on the instruction, forming the user area and/or the spare area in the data recording area of the mount storage medium. The spare area is to be used as a substitute if a defect exists in a recording unit of the user area.

摘要： Disclosed in a semiconductor laser device for use in a system or apparatus utilizing light for information transmission in optical communication or the like, in which lattice defects or the like are prevented from occurring in the vicinity of a light-emitting active area to thereby reduce a leakage current which substantially makes no contribution to light emission. In order to realize the above semiconductor laser device, a wide gap area for preventing a leakage current is formed to be flat or formed to be spatially apart from the active area.

摘要： A plasma processing apparatus which is effective for surface processing uses a reactive gas activated by plasma excited by microwave energy. Generation and maintaining of the plasma excited by the microwave energy are different where pressure in the gas chamber is above 0.1 Torr. Generating a high density plasma and maintaining the plasma includes the use of a protrudent window which extends into the activating chamber which also operates as a cavity resonator. Oxidation of resist formed on the surface of VLSI may be provided and damage by charge particles prevented by use of a magnetic field.
