摘要： The present invention relates to a method of recording marks representing data in an information layer of a record carrier by irradiating the information layer by means of a pulsed radiation beam, each mark being written by a sequence of pulses, the recorded marks being erasable by irradiating the information layer with an erase radiation beam. In order to achieve a reduction of the temperature of a transparent heat sink of a dual-layer optical recording medium without compromising the direct overwrite of old data, it is proposed according to the present invention that said erase radiation beam has a first erase power level (e1) for a first erase period (t1), a second erase power level (e2) higher than or equal to said first erase power level (e1) for a second erase period (t2), and a third erase power level (e3) lower than said second erase power level (e2) for a third erase period (t3).

摘要： Apparatus and method for selectively enabling writing of data multiple times onto a write-once read-many optical disk by a host system, the disk having a disk type indicator, and each sector having a SWF field and a flag field and user data, wherein new data bits replace existing data bits in a one-for-one ratio without mapping. The apparatus comprises an optical disk drive having: a spindle motor rotating an optical disk; an optical assembly/laser generating a laser beam adapted to heat a minute region on the optical disk; a bias magnet affecting the polarity of the heated region; a write/read channel driving the optical assembly/laser and bias magnet; a write/read controller adapted to process a unique erase command and thereby controlling the optical assembly/laser and bias magnet to write every user data bit of a sector to zero in a one-for-one ratio without mapping; and a small computer system interface receiving write commands from a host system.

摘要： Data is recorded on packet basis to a track of an optical recording medium and the data is pseudo-erased by erasing contents information of the track having the data. Information indicating the end position of the packet containing the data is recorded on the optical recording medium and a new data is recorded to the track where the data has been pseudo-erased in accordance with the information indicating the end position of the packet.

摘要： A data erasure device for an optical recording medium which controls the effects of a temperature rise of an optical recording medium during an erasure operation. The data erasure device irradiates a light beam on a recording medium, and erases data recorded on the medium by increasing the temperature of a portion of the recording medium irradiated by the light beam. The light beam is caused to blink between two states during the erasure operation to produce a uniform erasure mark.

摘要： A recording or erasing on a thermal recording medium is performed such a manner that a local region of a recording film on the recording medium is heated to a predetermined temperature to reversibly change the state of the local region between two states. In this method, the recording film is initialized in one of the two states. When the recording film is set in the other of the two states upon continuous or intermittent heating, a band-like region elongated in a recording direction on the recording film is formed to effect the erasing operation. In recording step, the local region of the recording film is heated to a predetermined temperature in accordance with information so as to include the band-like region in the local region to be heated and a state of the heated local region is caused to be identical with the state upon the initialization.
