Latest Patents

Cheng's latest patents include a method for detecting a contact event between a transducer and a recording medium. This method involves positioning a transducer that includes a writer, a reader, a heater, and a thermally responsive sensor. The process includes applying power to the heater to establish a fly height of the transducer, supplying a bias current through the thermally responsive sensor to generate a bias signal, and measuring a root mean square (RMS) voltage of the thermally responsive sensor based on the bias signal. The detection of a contact event is based on the threshold voltage being greater than a specified value.

Another significant patent involves controlling a heat resistive element with a pulse modulated signal. This innovation relates to pulse width modulating a power signal to a heat resistive element of a transducer. The power signal may be derived from a preamplifier and is used to control the heating of the heat resistive element based on its thermal time constant and adjustable components of the pulse width modulated power signal.
