摘要： A disc player for reproducing program information recorded on a disc in a plurality of partitions together with address data for each partition includes a program selection control for selecting one of the partitions, representing a particular program. A program selecting key causes a pick-up to be positioned at the address identifying the start of a selected partition the same as or reversed from a present partition. Multiple manipulations of the program selecting key cause the selection of a partition multiply reversed from the present partition. A second program selecting key causes the selection of a partition advanced from the present partition.

摘要： A system for recovering information from a videodisc and performing special functions which enhance the operational character of the system. To increase the reliability of landing at or near a target track, provisions are made to search for a track adjacent a target track whose track identifier has been obliterated. Further, a method and means for stepping forward or reverse one field at a time is disclosed. Another aspect of the invention concerns a capability to respond to a random command instruction resulting in subsequent functioning of the system in a random manner. Yet a further aspect of the invention is related to controlled jumping of one or more tracks during vertical blanking time to produce unique forward or backward motions; multiples of playing speed, both forward and reverse, and visual special effects can be realized using the multiple track jumping feature. Finally, a method and means are described which permit synchronous transmission of video from a videodisc to an external using device.

摘要： In a video disc mastering system, player control data is conveyed by a block code having framing and field number bits and data for use by a computer external to the player is conveyed by a convolutional code having no framing bits, having error check bits related to a subset of the field number bits conveyed by the player control data and having vertical parity selected to spread data required for predictive and reconstructive error correction over a number of video fields greater than that recorded on one convolution of the disc information track. Data is downloaded to an external computer for interactive player applications by means of a decoder which utilizes the player framing and field number codes conveyed by the player control data to recover the convolutionally encoded data as well as detecting tracking errors to provide a high data transfer rate, orders of magnitude of improvement in word error rates and facilitating new refinements in intrafield track error correction, namely, correction of intrafield track skips occuring after the player control data.

摘要： A method and apparatus for selectably retrieving information from any of a plurality of spirally-formed information tracks formed in a video disc by means of controlling a carriage for translating the video disc in a forward or a reverse direction relative to radiant beam information recovery means in a video disc player. Each information track is identified by a unique address and means are provided for selecting the address of a particular track to be retrieved. A prescribed sequence of drive signals is applied to a carriage motor dependent on the distance to be traveled by the carriage to retrieve the selected information, the drive signals being successively stepped downward to intermittently redetermine carriage motor speed as predetermined location thresholds are reached during carriage translation.

摘要： An adaptive video disc record stylus kicker system for inducing limited stylus translations radially across the disc record. Control circuitry responsive to disc track and disc angular sector identification signals automatically calibrates the kicker activation signals to produce a desired kicker induced stylus translation. A microprocessor establishes a table containing kicker control signals for driving the kicker in each sector of the disc. For a given kicker induced stylus translation, the error is calculated between the actual stylus translation and the programmed stylus translation and the control signal for the respective sector is adjusted accordingly. Subsequently the control signals for each of the other sectors are altered proportional to the adjustment made to the particular control signal in accordance with a correlation function.

摘要： A storage disk comprising at least one data track which is composed of spiral-shaped turns or concentrical turns, the data being arranged in the form of data blocks on the turns so that between the data blocks alternately a guide segment or a blank segment is present. The lengths of the unit, measured in angular degrees, consisting of data block and guide segment and the unit consisting of data block and blank segment are substantially the same and are chosen so that the same number of units is accommodated in each turn. The spirals are sub-divided into sectors which contain only data blocks or only guide segments or blank segments. In each sector containing guide segments the radial distance between these segments is substantially twice the distance between the data blocks in each sector containing data blocks. The invention also relates to a device for writing and/or reading data of a rotating disk as described, comprising a light deflection system which notably includes a slow light deflector and a fast light deflector, the latter deflector scanning the guide segments.

摘要： A magnetic disc has a plurality of video track segments for storing distinct fields of video information. A look-up track is provided on the disc and segmented to store indirect address data which may be represented by random numbers, and which are related to the video information fields. Both the look-up track segments and the video track segments are numbered sequentially. Each video track segment is permanently associated with a look-up track segment.A movable transducer is associated with both the video tracks and the look-up track. A counter circuit is provided to indicate periodically the instant look-up segment numbers with respect to the instant position of the rotating cyclical storage device and in synchronism therewith. A first comparator circuit compares an indirect address input request with the indirect addresses recorded on the look-up track. Responsive to an output from the first comparator circuit, a buffer circuit stores an instant look-up segment number and transfers it to a control circuit. A control signal from the control circuit is sent to a transducer positioning device which moves the transducer to the corresponding video track segment.A look-up decoder circuit is designed to sense a first empty segment automatically and periodically. A new video picture information is stored on the video track segment corresponding to that first empty look-up track segment.Data bits are stored on the back porch of the horizontal sync pulses on consecutive lines of the video information. A circuit is provided to extract these data bits and restore the look-up track if accidentally erased.
