摘要： A magneto optical disc system includes a disc having permanently recorded tracks overlain with magneto optical recording material. Data is recorded in the magneto optical material in tracks superimposed over the permanently recorded tracks, using the read-only data to define magneto optical tracks. The magneto optically recorded data is correlated with the prerecorded data for defining the location of data stored in the magneto-optic tracks.

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： 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： The invention concerns a high storage capacity ROM-RAM disk and a process for reading and writing to the ROM-RAM disk. T he aim of the invention is to devise a ROM-RAM disk and a process making it possible to read ROM and RAM simultaneously, to read the ROM area and at the same time write to the RAM area and to provide the largest possible volume of memory. The invention comprises two alternative designs. In a first design a ROM-RAM disk contains an area having both ROM and RAM memory structures as of a certain radius or diameter, establishing therein, at a constant rotational speed, a scanning/writing speed which ensures a reading/separation of the data stored in the ROM-RAM structures. In a second design, the available storage area is taken up entirely by a ROM-RAM storage area, where RAM memory structures have a reduced data rate in order to form, a length of memory structures necessary for separating the data stored in the ROM-RAM storage area.

摘要： A system for guidance of an optical scanning device is disclosed in which a gain factor (G factor) is responsive to a track error signal which is a function of the deflection of a scanning device. Deviation of the G factor setting from an optimum setting is automatically determined in conjunction with an open track control loop by driving a servo device (SV) to deflect an actuator from its neutral position and by evaluating a push-pull signal (PPTE). The G-factor is automatically set to an optimum value.

A second input of the comparator is connected to an output of the low pass filter, and a controls processor is connected to an output of the comparator. A second comparator may be provided with a first input connected to the output of the rectifier, whereas the second input of the second comparator is connected to a reference voltage. The output of this second comparator is also connected to the controls processor which recognizes the type of recording medium being scanned from the outputs of the comparators.

摘要： A circuit for reversing a magnetic field in which a bifilar coil is provided with a series of two oppositely-wound windings that are connected together at one end to form a junction. A source of current is connected in series with an inductive resistor, and this series circuit is connected at one end to the junction. At the other end of this series circuit, there is a voltage supply source. Each of the two oppositely-wound windings has its other end connected to a variable switch. The two variable switches have control inputs that are connected to two outputs from a control unit which applies a reference potential to each winding through the variable switch, so that all current from the source of current flows through each winding upon closure of the respective variable switch.
