The present invention relates to an apparatus for azimuth-recording data on a magnetic recording medium. Heads (13a) and (13b) having azimuth angles different from each other are used and data are recorded on and reproduced from a plurality of adjacent tilted recording tracks on a magnetic tape T. A recording-system encoder (23) converts data to a code sequence in which null points of frequency spectrums are respectively provided at null points of waveform equalization characteristics of partial responses such as PR1, PR4, etc. For example, record-coding using a 8/10MSN code is performed. A reproduction-system equalizing circuit (28) performs waveform equalization based on the partial responses. Further, a data detector (29) detects the data by a Viterbi coding method for executing state transition during which the characteristic of the code sequence is adopted. Azimuth-recording in a narrow track width can be easily achieved while a reduction in effective recording speed due to an increase in the azimuth angle is being controlled.

Azimuth magnetic recording and reproducing apparatus and method

Partial response (1, 1) is applied to a partitioned MSN (partitioned-matched spectral null) code. A branch metric (BM) obtained in a calculation block is directly supplied to a selector, and it is also supplied to the selector via an adder. The adder adds a predetermined value to the branch metric in such a manner as to decrease the degree of likelihood associated with a state transition corresponding to the branch metric. A determination block detects an invalid state transition in a detection trellis, which cannot be generated by the partitioned MSN code, on the basis of the number of 1s or 0s included in the partitioned MSN code. The selector selects either the branch metric added with the predetermined value or the branch metric added with no predetermined value depending on the detection result of the determination block. A path metric is calculated using the selected branch metric added with the predetermined value or added with no predetermined value.
