Abstract: The present invention relates to a method and apparatus for engaging a magnetic tape with a transducer at a read/write zone for achieving consistent head-to-tape coupling throughout the intended recording location, especially at the edges of the tape. The transducer, located on the end face of the rotating transducer carrier, reads and writes arcuate information tracks generally laterally across the tape. The transducer traces a substantially circular transducing path through the read/write zone with the axis of rotation corresponding substantially to the center of the transducing path. A tape support system generally adjacent to the read/write zone positions the tape so that the transducer penetrates into a tape surface along a read/write location.

Abstract: A digital signal, such as a PCM (pulse-code-modulated) digital audio signal, can be recorded with all samples in a predetermined data format so that it becomes possible to satisfactorily and accurately record and or reproduce PCM digital audio signals which are not synchronised with each other. During recording, the PCM signal is stored in a memory (21) in the form of blocks each including a plurality of signals. Addressing (32) of the memory (21) is arranged such that the symbols are interleaved over the extent of each of the blocks, and the blocks are divided into sub-blocks. The symbols are recorded in the sub-blocks with a respective plurality of different recording heads (9a, 9b, 9c). During reproduction, the recorded signal is reproduced by one of a plurality of different reproducing heads (13a, 13b, 13c; 15a, 15b, 15c). The symbols are de-interleaved by suitable addressing of the memory (21), and the signal is supplied to an output terminal (34).

Abstract: A digital VTR in which recording heads (51a and 51b), reproducing heads (52a and 52b), and erasing head (53) are arranged on a rotary drum (50) so that the recording heads (51a and 51b) and the erasing head (53) do not scan tracks while the reproducing heads (52a and 52b) scan a tracking area (2) and a sound area (3). When the sound signals of, say, channel number 1 are insert-recorded, a reproduced signal processing circuit (67) separates the sound signals of channel number 2 from interleaved sound signals reproduced by the reproducing heads (52a and 52b) and feeds the sound signals to a recording signal processing circuit (46) through a switch (45b). The circuit (46) interleaves the sound signals of channel number 2 and the sound signals of channel number 1 separately fed through a terminal (42a) and records the signals in the sound area (3) by means of the recording heads (51a and 51b). Therefore, no crosstalk of recorded signals and erasing currents occurs in the reproduced signals corresponding to the sound signals, ensuring the insert-record of ths sound signals. The S/N ratio of the reproduced signals does not lower due to crosstalk of the recorded signals and erasing currents and the sound signals of part of a plurality of channels can be insert-recorded.

Situated within a base (22) and cover (24) is a head carrier assembly (36) for recording data onto and playing back data from the data tape which advances in a longitudinal direction past the head carrier assembly. The head carrier assembly (36) includes an inside-out spin motor (40) for rotating the head carrier assembly and a pivot motor (72) at the rear of the head carrier assembly for pivoting the head carrier assembly in a plane perpendicular to the longitudinal direction of advancement of the tape (26).
