Magnetic head including two contact sensors |
摘要 |
A magnetic head includes a medium facing surface, a read head unit, a write head unit, and a protrusion device. The protrusion device causes part of the medium facing surface to protrude toward a recording medium. The read head unit has a first end face located in the medium facing surface and includes a first contact sensor for detecting contact of the first end face with the recording medium. The write head unit has a second end face located in the medium facing surface and includes a second contact sensor for detecting contact of the second end face with the recording medium. The first end face and the second end face are located at positions different from each other in a direction of travel of the recording medium. |
