摘要： A recording apparatus for recording digital signals to plural tracks formed sequentially on a tape using plural heads includes a first selector for selecting the first through n track sets, continuous tracks within the plural tracks formed on the tape. A disposer disposes the first through k separated high speed reproduction data areas to the same positions in each of the m tracks comprising the first through n track sets. A first recording unit records the same high speed reproduction data to the same track position in at least the tracks having the same azimuth within the m*k high speed reproduction data areas belonging to the same track set. A second selector selects the n+1 through n+N, each track set comprising M tracks selected from among the tracks to which the high speed reproduction data areas are not disposed. A second disposer disposes a continuous very-high speed reproduction data area to the same position in each of the M tracks forming the n+1 through n+N track sets. A second recorder record the same very-high speed reproduction data to the M very-high speed reproduction data areas belonging to the same track set within the M*N very-high speed reproduction data areas belonging to the n+1 to n+N track sets.

摘要： Recording apparatus for recording video signal on a tape by helical scan heads has a special frame data detector for detecting a special frame data that can be processed during a reproducing operation, without any additional data, to reproduce an image, a memory for storing the special frame data, and inserting arrangement for inserting a selected track after a predetermined number of tracks. One selected track is written with a portion of the special frame data repeatedly, and another selected track is written with another portion of the special frame data repeatedly, and so on. During the high speed reproducing mode, various portions of the special frame data as obtained from a number of selected tracks are gathered to form an image.
