    摘要： An optical disc on which data is recorded and/or from which the data is reproduced, includes a recording area where the data is recorded in at least one physical cluster, a defective area, where a defect that prevents a recording and/or reproduction of data is present, provided in the recording area, and a recording end area where information indicating an end of recording is recorded before the defective area. A method of recording data on and/or reproducing the data from a high density optical disc having a defective area, includes recording the data in a predetermined recording area having the defective area, and recording end data indicating an end of the recording before the defective area.

    摘要： An optical recording medium allowing data to be recorded on, erased from, and reproduced from, and storing information about power levels of an erase pulse. The recorded erase pattern information may include information about power levels of first and last pulses of an erase pattern for erasing data. The first and last pulses of the erase pattern can be differently set depending on the differing kind of recording layer or layers of a disk or differing kinds of disks and recorded in a reproducible only area or rewritable area of the optical recording medium. Thus, by presetting the appropriate erase power levels, the time required for selecting an optimal erase power for the optical recording medium can be considerably reduced.

    摘要： An optical disc includes tracking polarity information. The optical disc includes a clamping area, a lead-in area, a data area, and a burst cutting area (BCA). The BCA is present between the clamping area and the lead-in area and in which information regarding the optical disc is recorded, and the information is read before performing tracking in the data area. Accordingly, it is possible to obtain the tracking polarity information and/or reflectivity information without trial and error and directly record or reproduce user data in a data area of the optical disc.

    摘要： An apparatus to generate a seek direction detecting signal for an optical pickup to determine a position of a center of an optical spot focused on an optical disk relative to a center of a track, which focuses a main beam on a first optical detector and a sub-beam having a predetermined aberration in a radial direction on a second optical detector using a light dividing unit. The second optical detector has an inner and an outer pair of light receiving portions arranged along the radial direction, the inner pair being between the outer pair. A signal processing portion includes a first signal processing portion to detect a track error signal from signals output from the first optical detector, and a second signal processing portion to generate the seek direction detecting signal from signals detected by the second optical detector and the track error signal.

    摘要： An optical information storage medium and a method of recording thereon. The optical information storage medium has a lead-in area, a user data area and a lead-out area, and data indicating a maximum and/or a minimum writing speed, maximum and minimum writing speeds, or compatible writing speeds is recorded in a recordable region of at least one of the lead-in area and the lead-out area. The optical information storage medium and the method of recording on the media enable a disc drive to reliably record data on a disc which cannot achieve a prescribed recording speed due to manufacturing conditions, at an optimal speed considering the pre-recorded writing speed data.
