摘要

Video signal recording apparatus which has plural transparent recording modes (eg 25, 12.5 and 6.25 Mbps record modes) and in which bitstreams transmitted in digital form in the form of transport packets and subjected to intra-frame, intra-field, inter-frame or inter-field coding are recorded, is arranged to enable trick playback such as high-speed playback. Trick playback data is separated from the data to be recorded and recorded in a predetermined area on the record medium. The recording mode is detected 167 from the playback signal and in response thereto the running speed of the tape record medium is controlled. In addition the tape tracking is controlled so that a head scans a subcode area or a VAUX area in high-speed playback at a predetermined tape running speed in a detected record mode.
