Title: Data detector for detecting data in presence of control signals

Abstract: Systems, methods, and other embodiments associated with a data detector that processes signals read from a storage device are described. According to one embodiment, a detector for detecting a data signal embedded in a read signal from a storage device includes a signal estimator configured to generate an estimate of the control signal from the read signal by sampling the read signal to determine characteristics of the control signal. The read signal includes the data signal and the control signal. The signal estimator uses the characteristics to calculate the estimate of the control signal. The detector also includes a cancellation unit configured to produce the data signal by cancelling the estimate of the control signal from the read signal.
