ABSTRACT:
A data recording system includes media such as a magnetic disk or tape, a read/write head assembly, and a circuit that provides a write signal having edge placement equalization. The circuit responds to a binary serial data signal such as a run length limited signal of the type (1,x) and provides a write signal having data transitions corresponding to one of the two binary data values, the absence of a transition corresponding to the other data value. In addition, the write signal is provided with a pair of equalization transitions during periods of no data transitions. A first data transition is shifted away from the last provided equalization transition by a predetermined offset. A second data transition, provided immediately after the first data transition, may be shifted toward the last provided equalization transition. Timing of the data transitions is derived from a clock used to provide the equalization transitions.
