摘要:
In an information recording medium for recording and reproducing data thereon on a sector-by-sector basis, the recorded data being managed as at least one file by using a file structure, the file structure includes unused space management information for identifying a used region and an unused region. At least one defective region is registered as an unused region in the unused space management information, the at least one defective region being a region on the information recording medium which is incapable of proper reproduction of the recorded data.

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.

An information recording disc has a burst cutting area (BCA) for recording control information for a reproducing apparatus be removing a reflective layer of the disc in a striped shape and a data recording area for recording user data. The burst cutting area includes at least one BCA control information area. The BCA control information area has an application identifier area for identifying applications of control data, a data length area for indication data length of the control data, and an application specific data area data area recording the control data. Also, an information reproducing drive reproduces data from the information recording disc.

An information recording medium includes a disk information area; a user area including a plurality of sectors; and a spare area including at least one sector which, when at least one of the plurality of sectors included in the user area is a defective sector, is usable instead of the at least one defective sector. The spare area is located radially inward from the user area. A physical sector number of a sector to which a logical sector number “0” is assigned, among the plurality of sectors included in the user area and the at least one sector included in the spare area, is recorded in the disk information area.

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.

摘要:
In a cluster ion beam irradiation apparatus including an apparatus for measuring size and energy distribution of gas cluster ions by using the time of flight (TOF) mass spectrometry, a unit for applying a retarding voltage is disposed in a stage preceding a TOF measuring instrument including a drift tube and a current measuring instrument. By measuring the size and energy distribution of the gas cluster ions and adjusting ionization conditions, cluster ions having predetermined energy and size are supplied to a work surface. In addition, a product of a pressure in an ion transportation device and an ion transportation length is controlled so as to satisfy the relation P×L≦30/N2/3/E1/2 Pa·m, where N is the size of gas cluster ions used for irradiation, and E is kinetic energy (eV) of the gas cluster ions.
