| 摘要 |
A decoding technique applicable to binary data encoded by phase encoding (PE), frequency modulation (FM), or modified frequency modulation (MFM). Resynchronization of the decoding clocking circuitry occurs upon every flux transition, rather than at less than all flux transitions, such as only at each data flux transition in the case of phase encoding. The technique provides substantially greater velocity tolerance than previous techniques for decoding codes encoded in this manner.
