摘要： An optical pickup provided opposed to an optical disc D is moved in the optical axis direction with a drive signal from a focus search circuit to detect, with an amplitude detecting circuit, the character “S” shape waveform of large amplitude corresponding to the recording surface of optical disc of the focus error signal FE obtained from the optical pickup and such detected output is counted by a counter. When the character “S” shape waveform of large amplitude appears twice, an interval thereof is measured with a time measuring circuit and width of interval is detected with an interval detecting circuit. The counted value of counter and detected output of the interval detecting circuit are supplied to a microcomputer to automatically detect a type of optical disc. Thereby, a reproducing device which can be used for a plurality of reflection type optical discs may be structured.

摘要： A recording and reproducing or observing apparatus based on a laser beam deflection detection method in which an object has a very small area for reflecting light. A laser beam emitted by a semiconductor laser diode passes through a collimator lens and a stop. The beam passes through the lens and stop and is reflected by a polarization beam splitter and focused by an objective lens onto a surface of a cantilever. Reflected light from the cantilever surface is focused by the lens before being received by a position sensor. Either the incident light or the reflected light passes through an optical path that is substantially 90 degrees relative to the optical axis of the other light.

摘要： A method and apparatus for controlling an optical output of a laser diode. Writing or erasing optical outputs of a laser diode are controlled during a mirror region interval of a header within an optical disk, under a continuous optical output state of the laser diode. A change in the optical output caused by heat of the laser diode is compensated by comparing the writing and erasing optical outputs with corresponding preset writing and erasing optical output values.

摘要： A method for calibrating a tilt in a disc player includes a disc insertion judgment step, a focus error output time judgment step, a subtraction step, a disc recording surface judgment step, and a tilt calibration step. In the focus error output time judgment step, an optical pickup unit is made to ascend and then descend for a predetermined time, to then judge a first focus error output time at which a focus error is output during ascending and a second focus error output time at which a focus error is output during descending. A focus error output difference time is obtained by subtracting the FET1 from the FET2. In the tilt calibration step, if the FET is not same as a reference focus error output difference time (FETrf), the turntable is made to rotate, to calibrate a tilt between the optical pickup unit and the disc.

摘要： The present invention provides a single information recording and reproducing apparatus that is used to record data to multiple disks that are to be recorded on using different wavelengths. More specifically, the present invention provides an apparatus that accurately discriminates disk types while preventing disk damage and accidental recording of data during the disk type discrimination operation. The disk type is determined using the intensity of light reflected from the disk. Information is encoded using an encoder corresponding to the disk type. The resulting signal is used to drive a laser corresponding to the disk type, and information is recorded.

摘要： The invention relates to a method and a device for recording an information signal 10 in a phase change layer of a recording medium. A mark is recorded by a sequence 13 of write pulses and previous marks between the marks to be recorded are erased by a sequence of erase pulses 14. De bias power level 191, 192 between the erase pulses is made dependent on the recording speed, thus obtaining low jitter of the recorded marks and at the same time preventing thermal cross write during erase.
