Abstract: A head wheel is rotated at a predetermined, essentially constant speed within a tape cylinder over which a tape is guided in a spiral path, on which video signal tracks are recorded in inclined track portions. The instantaneous position of the head wheel is determined, for example by a tacho generator applying signals to a counter, phase-synchronized by the outputs from the head wheel tacho generator.
Abstract: An integrated circuit programmable read only memory is arranged in a matrix aving a plurality of memory cells arranged in rows and columns. A particular cell in a matrix is addressed by selecting the appropriate row and column. A destructible memory element connects a column to a row at each intersection. The currents for programming adjacent memory cells corresponding to a row of the memory are diverted by a single path.
