| 摘要 |
<p>The present invention relates to circuitry for processing an analog read signal, such as a signal produced by a magnetoresistive head (18), in a magnetic data storage system. The circuitry processes an analog read signal before the signal reaches an analog to digital converter (54). In one embodiment, the invention comprises circuitry (44) for equalizing the amplitudes of the positive and negative pulses in the analog read signal. In another embodiment, the invention comprises circuitry (42) for reducing the baseline shift of the analog read signal. The invention may be used in magnetic data storage systems using any conventional data detection method.</p> |
