摘要： A receiver/recorder for television transmissions whereby continuous recording of television transmission occurs from at least one channel onto a random-access rewritable recording medium. At each of a plurality of predetermined locations a binary code is periodically written to represent a filling of predetermined portions corresponding respectively to the predetermined locations. An indexing device responds to the binary code in order to automatically distinguish between a first in time recorded transmission on the medium from a second in time recorded transmission on the medium at a particular one of the predetermined locations.

摘要： A process for producing a thin-film magnetic tape head includes the steps of coating a substrate with a layer of material which protects the substrate from an etchant. A cavity is etched into the substrate and a prismoid of magnet material is deposited in the cavity. The sides of the substrate are removed so that the prismoid projects above the sides for a substantial portion of the height of the prismoid. The substrate is coated with a gap-coating layer and the gap-coating is removed from one side of the prismoid. Another layer of magnetic material is deposited onto the substrate and various parts, such as pole shoes, are formed. The substrate is polished and the apex of the prismoid is removed. Head windings are made. A return path for the head windings is provided by depositing another layer of magnetic material onto the substrate. A protective layer of a metal oxide is deposited onto the substrate.

摘要： An arrangement for selectively playing back and recording data in which a rotating disk-shaped recording medium is provided with data storage tracks. An optical system reads the stored data by guiding a light beam along the data storage tracks. The data read by the optical pickup system is decoded by a decoder which has an error output that emits a pulse for every bit error. The light beam strikes the disk-shaped recording medium at an angle and has a vector component which is tangential to the recording medium or disk, so that when the angle is 90.degree., the vector component is zero. The bit errors are applied to a counter that provides the corresponding bit-error rate and provides a signal for controlling the adjustment for varying the vector component so as to maintain the bit-error rate below a predetermined threshold.

摘要： The present invention relates to an optical recording medium having at least two information carrier layers, on which information can be written by means of a focused light beam. In this case, a separating layer is arranged between the information carrier layers and a respective transparent covering layer is arranged between the information carrier layer and the surface of the recording medium, the thickness of which covering layer substantially exceeds that of the information carrier layer. One object of the present invention is to propose an optical recording medium in the case of which it is possible to write to both information carrier layers using a low optical power. Further objects of the invention are to specify an apparatus and also a suitable method for writing to a recording medium of this type. A recording medium according to the invention has information carrier layers which are both semi-transparent.

摘要： Apparatus for interposing additional optical elements in the optical path of an optical read/write device includes said additional element mounted on a carrier pivotally mounted on a lens carrier which is subject to lateral translation. Stops on the carrier to which the additional element is mounted engage actuators arranged at the limits of lateral travel of the lens carrier, which limits are beyond the recordable areas of the recording medium. The engagement of the actuators with the carrier causes the carrier to pivot and either insert or remove the additional optical element in the optical path of the apparatus. Magnetic retainers are included to prevent the additional element from moving from the desired position.

摘要： A cassette for use with a recording apparatus comprises: a housing for a recording medium, the housing having a first surface and side walls, the recording medium being accessible through one of the side walls; at least a part of a chip card affixed to the housing, forming a second surface of the housing and closing the cassette, the chip card part having a memory formed integrally therewith and externally accessible contacts; and, the contacts of the chip card being positioned on the second surface to be engageable by corresponding contacts in the recording apparatus when the cassette is inserted therein. One of the side walls has an access door for the recording medium and the second surface forms an upper wall of the housing as defined by the access door. The part of the chip card forming the second surface of the housing has a marking position at which light transmissivity can be controlled. The marking position can be rendered non transmissive to light to prevent recording.
