Abstract:
An apparatus for recording a digital signal on a magnetic recording medium, wherein the digital signal can be reproduced from the magnetic recording medium by a partial-response detection system ""PR(1, 0, -1)"", the apparatus comprising:an amble generator for generating an amble signal representing a bit-sequence amble pattern, wherein the bit-sequence amble pattern can be detected and reproduced by the partial-response detection system ""PR(1, 0, -1)"" as a detected amble pattern having a period of state inversions which is shorter than a period of state inversions in the bit-sequence amble pattern represented by the amble signal generated by the amble generator;means for combining the amble signal generated by the amble generator and a first digital information signal into a second digital information signal on a time sharing basis; andmeans for recording the second digital information signal on the magnetic recording medium.
