IPC: H03M7/46
Filed: 1988-03-01
Abstract: PURPOSE:To obtain a code with minimum magnetization inversion interval (Tmin) of 1.33 times the on-going (2, 7) code and double the MFM by selecting a code word limiting the number of run of '0' at the start and end of the code word and possible to be decoded uniquely.
