Abstract

A magnetic sheet control member, for use in a device for recording and reproduction using a magnetic head in sliding contact with a rotary flexible magnetic sheet, to guide the magnetic sheet to the magnetic head by a negative pressure, having upstream-side and downstream-side inclined surfaces disposed respectively at the upstream side and the downstream side with respect to the rotation direction of the magnetic sheet and inclined to become more distant from the free rotary surface plane of the magnetic sheet towards the downstream side, and stabilizing surfaces disposed respectively at the outer side and inner side with respect to the radial direction of the magnetic sheet to connect the upstream-side inclined surface and the downstream-side inclined surface, thereby obtaining a stable head contact over the entire recording area from the innermost side to the outermost side of the magnetic sheet.
