摘要：Phenomena of shifting of magnetization reversal points called a pattern peakshift and a stream shift which occur when digital data consisting of \"0\" bits and \"1\" bitsrecorded on a record medium at a high density is reproduced are resolved by

discriminating whether the digital data to be recorded includes a bit pattern which causesthose shifts or not, and for the digital data which may cause such shifts, recording thedata at a timing such that the shifts are cancelled when the data is reproduced. Thus, thedigital data recorded at the high density through a narrow discrimination window can beprecisely reproduced.
