发明名称 Recording and reproduction of an information signal in a short play and a long play mode
摘要 An apparatus for recording an information signal forming slant tracks (Ti) on a magnetic record carrier (16), and for recording a control (CTL) signal forming a longitudinal CTL track (50). At least one write head (10) located on a rotatable head drum (14) writes the information signal on the record carrier to produce the slant tracks, while a CTL write head (34) writes the CTL signal at a specific frequency on the record carrier. In a first recording mode, a portion of the information signal is recorded by the write head (10) to produce a track during each revolution of the head drum on the record carrier, the frequency of the CTL signal being such that an edge in the CTL signal is written in the CTL track for each of the tracks, and the record carrier (16) being transported with a predetermined first speed, and the head drum (14) being rotated with a predetermined rotational velocity. In a second recording mode, the information signal produces a track of information during each n-th revolution of the head drum (14), while the record carrier is transported at a second speed substantially equal to the first speed divided by n, in the second recording mode, and the head drum is rotated at the same predetermined rotational velocity.
