摘要： There is provided a method to be applied to a tape recorder of the type for storing and retrieving reference signals on a plurality of tracks of a magnetic tape by a magnetic head comprising, as integral parts thereof, writing sections and reading sections arranged at a given pitch for at least two channels for detecting a signal on a reference position of a track by a related one of the reading sections of the magnetic head for each channel. This is done by moving the magnetic head in order to detect the positional relationship between the related writing and reading sections of the magnetic head and the track on the magnetic tape for each channel. With such a method, the track-seek operation for locating the track and, hence, the data reading operation by use of a data backup tape recorder of the above described type can be accurately carried out on the basis of the positional relationship and, consequently, the number of unsuccessfully attempted reading operations as well as hard errors due to such operations can be effectively reduced.
