Abstract
A read channel (18) having a waveform sampler (58) is provided for use in a disk drive mass storage system (30). The disk drive mass storage system (30) includes a disk/head assembly (12), a preamplifier (14), and a control circuitry (11). The read channel (18) is coupled to the control circuitry (11) through a data/parameter path (13). The read channel (18) includes a plurality of circuit modules for processing a waveform data signal received from the preamplifier (14) and to generate a digital data signal in response. The read channel provides the digital data signal to the control circuitry (11) through the data/parameter path (13). The read channel (18) also includes the waveform sampler (58) for receiving and sampling a processed waveform signal from one of the plurality of circuit modules and for generating a digital waveform sampler signal in response. The read channel can provide either the digital data signal or the digital waveform sampling signal as an output onto the data/parameter path (13).
