摘要： In an apparatus for recording and/or reproducing signals on a flexible disc which is rotatably mounted in a jacket having an indicator for indicating the number of tracks on which the signals have already been recorded, a transducer records and/or reproduces the signals on a surface of the disc so as to form a plurality of circular tracks thereon. The transducer is subsequently moved in the radial direction of the disc to the next adjacent track. The apparatus is further provided with an indicator driving mechanism for driving the indicator of the jacket to shift the latter to a corresponding position as related to the number of the recorded tracks. The indicator driving mechanism is driven in synchronism with the movement of the transducer.

摘要： A magnetic disk assembly is comprised of a magnetic disk and a hub member centrally positioned on that disk and having a non-circular opening for receiving a circular drive shaft which serves to rotatably drive the magnetic disk. The hub member includes at least two reference surfaces which converge toward each other and which form two respective walls of the opening, and one or more resilient members having a surface which forms a third wall of the opening. The three walls are positioned and dimensioned such that when a circular drive shaft is received, the reference surfaces and the surface of the resilient member all tangentially contact the drive shaft to be rotated thereby when the drive shaft rotates.

摘要： A still image playback apparatus which has a single playback head which is mounted on a head positioning means adjacent a magnetic disc which is rotated at the field frequency and wherein the disc has a plurality of concentric tracks each of which carry video signals of one field. The playback head is moved by the head positioning means from one of the tracks to an adjacent track so that video signals of one still image corresponding to two field periods of standard television signals are obtained during playback from the playback head when the disc has been rotated twice.

摘要： A motion picture film having digital audio data recorded in at least one sound track thereof. Such digital audio data includes a plurality of bytes of data each having 8 bits of data. Each respective bit of each byte of audio data is recorded in a sound track of the film in the film running direction and each byte is arranged side-by-side in a direction normal to the film running direction to form a compression processing block. C1 parity data is added to each such compression processing block and C2 parity data is added after a predetermined interval of plural compression processing blocks. Error correction may be performed by utilizing the C1 and C2 parity data for each compression processing block and at the predetermined interval of plural compression blocks.

摘要： A motion picture film is provided on which a digital sound track for audio data is formed along the film running direction. Data tracks are disposed in the digital sound track along a direction normal to the film running direction and extend in the film running direction. A data pattern having a block of audio data is recorded in the data tracks, along with tracking patterns representing each data track. Each of the tracking patterns is recorded at one side of the data track along the film running direction with an offset in the film running direction of one half the width of a data track from the center of that data track.
