Claims

[Scope of utility model registration request]

In a seat pad of a magnetic recording and reproducing device that faces a magnetic head via a rotating magnetic sheet, a recess is provided in a portion of the seat pad opposite to a sliding contact position between the magnetic sheet and the magnetic head, and a recess is provided in a portion of the seat pad that is opposite to the sliding contact position between the magnetic sheet and the magnetic head. a protrusion having a reference surface that asymptotically approaches the sheet as the surface facing the sheet approaches the sliding contact position on the upstream side in the sheet rotation direction; and a protrusion facing the sheet on the downstream side in the sheet rotation direction from the sliding contact position A magnetic field characterized in that the surface has an inclined surface that asymptotically approaches the sheet as the surface moves away from the sliding contact position, and a ridgeline portion thereof is provided with a protrusion in the form of a pattern that protrudes toward the magnetic head side relative to the reference surface. Seat pad for recording/playback equipment.
