Clearance change between a magnetic head with a thermal flying-height control (TFC) function and a magnetic disk at high altitude was investigated. To clarify the change of head-disk clearance in the case of TFC actuation at high altitude, head-disk clearance change was experimentally evaluated as a function of altitude and head-disk clearance by using a TFC function. The evaluation results show that the head-disk clearance change is larger in the case with TFC actuation at high altitude than that in the case without TFC actuation.
