Patent ID: 8879189

Claim:
A magnetic head slider, comprising: two units, each unit comprising: at least one magnetic head element chosen from the group consisting of: a write element configured for writing data to a magnetic recording medium and a read element configured for reading data from the magnetic recording medium; a heater element configured for controlling a flying height of the at least one magnetic head element above the magnetic recording medium; a contact sensor element configured for detecting contact between the magnetic head slider near the at least one magnetic head element and the magnetic recording medium; a resistive element configured for regulating current through the contact sensor element, the resistive element being positioned in series with the contact sensor element; and a shared terminal configured for supplying voltage to the heater element and for conveying signals from the contact sensor element; and a shared ground terminal coupled to the heater element and the contact sensor element of both units and configured for acting as a ground therefor, wherein a series combined resistance of resistances from the contact sensor element and the resistive element is about 21.5 kΩ or about 25 kΩ.
