Programmable write equalization for magnetic data recording |
摘要 |
A circuit and method for generating write compensated write data signals in magnetic data recording. The circuitry is programmable to enable generation of write compensation meeting a variety of write compensation specifications. In particular, the circuitry can be programmed to generate extra write pulses, to adjust the pulse width and to adjust the pulse spacing within data cells. In an example embodiment, an input waveform drives a reset input on a state machine. An output waveform shape is stored as a pattern of bits in a register. The state of the state machine determines which register bits are selected by a multiplexer for output as a new write compensated write data signal.
