摘要： An optical pick-up for selectively reading and writing an optical and magneto-optical recorded medium, in which light projected on the recorded medium is reflected therefrom and directed onto one of two photodetectors, depending on the polarization of the light. The recorded medium has magnetic domains for storing data and a magneto-optical signal is generated from the difference between the two photo voltages from the two photodetectors. The magneto-optical signal represents the data stored in the magnetic domains. The recorded medium also stores data in pit forms, and an optical signal is generated from the sum of the photovoltages of the two photodetectors, to represent the data stored in the pit forms. The arrangement is suitable for reading out simultaneously the optical signal and the magneto-optical signal.

摘要： An optically-recorded medium in which a reflecting optomagnetic layer is applied to a transparent substrate layer. The recorded medium stores data magnetically and by pits. The magnetically stored data and the pit stored data are superimposed on each other, so that every spot and region on the recorded medium stores both magnetically stored data and pit stored data. The recorded medium is not divided into separate regions for magnetically stored data and pit stored data, and the magnetically stored data and pit stored data may be read out simultaneously by a single light beam.

摘要： An optical pick-up for selective playback and recording on a magneto-optically recording medium, in which light is projected from a source onto the medium. The light is provided with a direction of a polarization, and is either reflected from the recording medium or is transmitted through the medium. The reflected or transmitted light becomes deflected onto a predetermined one of several photodetectors, depending on the direction of polarization of the light. The intensity of the reflected light or the transmitted light is held constant to minimize noise components that result from the optical properties of different recorded media as well as from the light. By holding the light intensity constant, moreover, precise readjustment to each of the different recording media that may be used, is not necessary.

摘要： An optical scanning system for a compact disc having a sinusoidal data track radially meandering, at a selected frequency, about the axis of rotation of the disc includes a first laser beam for reading data from the data track. A +1 level laser beam and a -1 level laser beam respectively track the opposite edges of the data track and generate a tracking error signal. The +1 level laser beam and the -1 level laser beam are separated, with respect to the disc, by a distance equal to an odd integer multiple of one half the wavelength corresponding to the selected frequency. The +1 and -1 laser beams are not modulated by the sinusoidal data track and standard tracking circuitry can be used to track the data track.

摘要： A scanning device for recording/reading data in data tracks of a recording medium includes a light source supported by a tracking head for guiding a light beam along the data tracks. The data tracks are rotated and the beam is focussed onto the data tracks. The light source is moved at an angle .alpha. with respect to the radial direction of motion of the data tracks. An optical element directs the light beam to the recording medium and directs light reflected from the recording medium to a detector. An astimatic element is arranged between the optical element and the detector. The scanning device is improved in that the astimatic element has one axis arranged at the angle .alpha. with respect to the radial direction of motion.

摘要： A lens position signal LCE which indicates the discrepancy between the lens and its geometric mid-position is required for coarse tracking of optical storage drives. The prior art is for the lens position signal LCE to be formed in three-beam pick-ups by weighted combination of specific photodetector signals from a primary beam and secondary beam. The only way to ensure that the lens position signal is free of crosstalk caused by the tracking error signal is for the weights to be set correctly. The invention describes methods by means of which the weights can be adjusted automatically and can be matched to the characteristics of the pick-up and of the respective storage medium. The amplitudes of those components in the main and secondary beam signals which are dependent on the tracking error are measured, and the matched weights are determined from them by joint evaluation. Evaluations with synchronous detection and with time integration are described, some of which can be used during writing and reading.

摘要： The invention relates to a method for optimized tracking of an optical scanner along a track of an optical recording medium, the track having information markings arranged in dense succession, and also having fundamental changes in properties in significantly lower density. The method has the following steps: formation of a track error signal, detection of the occurrence of fundamental changes in properties of the track, formation of an offset value from the comparison of the value of the track error signal that occurs shortly before and shortly after the fundamental change in properties, formation of the track error signal, taking account of the offset value and repetition of the aforementioned steps.

摘要： The address information of DVD-R or DVD-RW discs should be identified more accurately. Therefore, the detector is implemented with a sample/hold device for storing a reference value to be used for a sampling window. An optional integrator is used for comparing the integrated signal with a reference value to decide on the presence of a land pre-pit. The timing for controlling both the sample/hold device and the integrator is derived from a phase locked loop that is locked to the incoming groove wobble signal (TWin) by performing a clock multiplication with a predetermined factor. Advantageously, no band pass filter has to be included, which would need to be tuned according to the variations of the disc speed. Furthermore, the proposed land pre-pit detector is less affected by variations of the input amplitude, as no limiter is used.
