ABSTRACT:
A data detection circuit for a read channel that recovers data encoded as the presence or absence of flux transitions on a magnetic recording medium, compares a current data sample of a read signal with a previous data sample and a threshold to determine whether the previous data sample represents a flux transition. The use of two data samples in the determination of flux transitions provides a more accurate detection of the data than comparing a single data sample to a threshold value. The data detection circuit generates an output data signal having data values based on the determined flux transitions of the data samples.
