摘要： An information read/write device has a first processor for instructing a second processor to write information onto or read information from a recording medium. The recording medium has a random access memory module which allows both processors to read or write data to the memory module. The second processor controls a scanning module for the recording medium, a write signal processing module and a read signal processing module. The read/write device is easy-to-operate while using a minimum of electric power consumption with prevention against electromagnetic interference (EMI) making the invention suitable for use in hand-held devices.

摘要： A disk drive. The disk drive includes a non-volatile memory that is incapable of being overwritten more than a limited number of times, a disk and a controller. The controller includes a memory management table used to manage a correlation between a logical block address (LBA) and a physical address of the non-volatile memory. In the absence of a replaceable region in the non-volatile memory and in response to an occurrence of a failure to write data in a region, defined as a failure region, in the non-volatile memory at a first physical address correlated with a first LBA, the controller is configured to write the data at a second physical address correlated with a second LBA of the non-volatile memory different from the first LBA, and is configured to correlate in the memory management table the first LBA with the second physical address.

摘要： Recording information is disclosed in which an information recording medium is irradiated with a recording energy beam that is power-modulated into at least a record power level and a record-ready power level lower than the record power level. The information is recorded on the recording medium in the form of length and interval of a mark portion. When forming a mark portion of a predetermined length, the radiation energy of the energy beam is increased as compared with when forming a mark portion of a different length before or after the first pulse of an energy beam pulse train including at least a pulse for forming the mark portion.

摘要： Embodiments in accordance with the present invention relate to methods wherein a capacity of a disk drive is increased by partially overwriting adjacent tracks to shorten the track width and collectively updating a data update unit made up of a plurality of tracks, wherein the capacity reduction caused by a defective track is suppressed. Track groups having two types of track widths, or Shingled Tracks(ST) and Tiled Tracks(TT), are allocated in a zone. First, the zone is divided into two areas, namely, a shingled track (ST) area and a spare or tiled track (TT) area. When a defective track is detected in the shingled track (ST) area, it is checked whether or not the spare or tiled track (TT) area affords an area to be transferred. If it does, an area is transferred from the spare or tiled track (TT) area to the shingled track (ST) area. When it is confirmed that the allocation of ST has been completed, TT is allocated to the remaining spare or tiled track (TT) area in subsequent steps.

摘要： A method for recording information is disclosed in which an information recording medium is irradiated with a recording energy beam power-modulated into at least a record power level and a record-ready power level lower than the record power level. When forming a mark portion of a predetermined length, the radiation energy of the energy beam is increased as compared with when forming a mark portion of a different length before or after the first pulse of an energy beam pulse train including at least a pulse for forming the mark portion. Also, only in the case where the energy beam is modulated by the power lower in power level than the record-ready power level after the last pulse of the energy beam pulse train including at least one pulse for forming a mark portion and the mark portion is followed by a space portion of a predetermined length, the particular radiation energy of low power level is reduced as compared with when the mark portion is followed by a space potion of a different length. The radiation energy is increased and/or decreased.
