Patent ID: 8773801

Claim:
A magnetic-recording head with a first thermal fly-height control element and an embedded contact sensor element configurable as a second thermal fly-height control element, said magnetic-recording head comprising: a write element configured for writing data to a magnetic-recording disk; a read element configured for reading back data from said magnetic-recording disk written by said write element; a first heater element configured as said first thermal fly-height control element to coarsely adjust a fly-height of said magnetic-recording head with respect to said magnetic recording disk; and said embedded contact sensor element configured to detect a contact with said magnetic-recording disk, and configured to function as said second heater element, said second heater element configured as said second thermal fly-height control element to finely adjust said fly-height; wherein said first heater element is configured to produce a first stroke-length larger than a second stroke-length of said second heater element for adjusting said fly-height.
