摘要： An error signal detecting apparatus for an optical recording/reproducing apparatus, the error signal detecting apparatus including a photodetector to receive light reflected and diffracted by a recording medium, and a signal processor to detect an error signal by calculating a detection signal of the photodetector. The photodetector includes a plurality of light receiving areas to independently receive light of a light area in which the profile of the light changes to the opposite profile according to the tangential tilt of the recording medium. The signal processor detects a tangential tilt error signal from detection signals of the light receiving areas. Thus, a signal output from the error signal detecting apparatus does not change when a shift is generated in the objective lens or the distance between the objective lens and the disc is deviated from the on-focus position. Also, a change in the profile of the light beam according to a relative tangential tilt with respect to the objective lens of a recording medium in land/groove format can be properly detected so that an accurate tangential tilt error signal can be detected.

摘要： An adaptor includes a sensor hole to be open/closed, and a method and an apparatus drive the adaptor. The adaptor includes at least one sensor hole determining the size of a disc received in an adaptor body which is received via a disc holder. The disc holder includes an elastic press extended therefrom and elastically support the disc, preventing a movement of the disc until the disc holder is inserted into the adaptor body. Further, a release is disposed on the adaptor body to release the disc from the elastic press when the disc holder is inserted into the adaptor body. A method for driving the adaptor includes determining whether the sensor hole is open; and determining the type of device inserted into a disc drive. The type of drive inserted into the disc drive is determined by the adaptor accommodating an 8-cm disc when the sensor hole is open, while a cartridge accommodates a 12-cm disc when the sensor hole is closed. An apparatus for driving the adaptor includes a sensing switch to be selectively inserted into the sensor hole of the inserted adaptor to be turned on/off and transmit the corresponding signal regarding the open/closed state of the sensor hole to a microcomputer.

摘要： An optical recording/reproducing apparatus for determining a direction in which an optical pick-up moves, and detecting a track cross signal. The track cross signal is useful as a basis of determining tracking pull-in after searching a track. In the present track cross signal detecting method, the track cross signal is obtained by binarizing the envelope of an RF signal RF0 obtained by subtracting some light receiving signals generated by some light receiving devices in the radial direction from other light receiving signals generated by other light receiving devices in the radial direction. The light receiving signals originate from a photodetector, divided into two or more sections in the radial direction. The track cross signal detecting method is especially useful for generating the track cross signal when the track pitch is smaller than the size of an optical spot, the signal being less affected by crosstalk caused by an adjacent track.

摘要： A recording medium having a spare area for defect management, and a method and apparatus for allocating and assigning the spare area. A plurality of zones are formed as one group without prescribing the relationship between a zone and a group. Spare areas include a spare area for slipping replacement and a spare area for linear replacement. The spare are for slipping replacement is first allocated, and the spare area for linear replacement is allocated according to the size of an area remaining after the spare area for slipping replacement is used and the purpose for which a disc is used. When the spare area for linear replacement becomes deficient during use of the disc, a supplementary spare area for linear replacement is allocated in sequence from the rearmost of a logical file area, such that the spare area can be more flexibly and effectively allocated.
