Abstract
A magnetic recording/reproducing apparatus is disclosed wherein reproduced signals read out from a plurality of recording tracks using a reproducing head can be separated into original recording signals of the recording tracks. Upon recording, an identification signal which has a recording wavelength equal to or greater than a minimum recording wavelength and causes no interference of any of the recording tracks with any adjacent one of the recording tracks is appended to and recorded together with a recording signal in order to allow, upon reproduction, acquisition of the position information of the reproducing head with respect to the plural recording tracks of the magnetic recording medium. Upon reproduction, a reproduced signal for each of the recording tracks of the magnetic recording medium is generated on the basis of the positional information read from the recording tracks.
