Abstract:
1. A disk controller comprising: a write signal generator for generating a write gate signal based on a media event trigger, wherein the write signal generator is further operably to assert an early write gate signal based on a media event trigger, deassert a post write gate signal based on a write field length, and generate the write gate signal by combining the early write gate signal and the post write gate signal and wherein the media event trigger is generated when a media event count compares favorably to a count from a sequence of counts; a read signal generator, operably coupled to a read/write bit clock, for generating a read gate signal based on the media event trigger and a read/write bit clock; and a read/write channel, operably coupled to the write signal generator and the read signal generator for adjusting the read gate signal based on the read/write bit clock to avoid a write splice period.
