Abstract

The authors measured the ontrack and offtrack error-rate performance of several combinations of experimental heads and disks using a partial-response channel at approximately 1 Gb/in². The system components include a magnetoresistive head, a thin-film disk, and the partial response readback channel. Precompensation and equalization were used to tune the channel for best performance. Results indicate that these components can write and read data at 1 Gb/in² with good error rates and offtrack margins
