Abstract:
A magnetic recording and reproducing apparatus which records and reproduces information in a manner such that one frame consists of a multiple of an even number of tracks, the magnetic recording and reproducing apparatus comprising:means for recording information on a magnetic tape by a recording head to form tracks successively, the information being recorded including a pilot signal having tracking information and track numbers that show a track order;means for reproducing the recorded information by a reproducing head to form a reproduced signal and for processing the reproduced signal, the reproducing means including means for demodulating the reproduced signal and for detecting track numbers from the reproduced signal;means for detecting the pilot signal from the reproduced signal, for obtaining tracking error information based on the detected pilot signal, and for performing tracking between the reproducing head and the track of the frame being reproduced by using the tracking error information; andmeans for generating a reference frame pulse, the reference frame pulse being used to perform signal processing in a reproduction/processing mode, the reference frame pulse generating means setting a phase of the reference frame pulse to correspond to a track phase of a predetermined track number among track numbers detected by the track number detecting means and said reference frame pulse generating means providing the reference frame pulse to the reproduction/processing mode.
