A master information carrier has a shape pattern corresponding to an information signal array to be recorded on a magnetic recording medium, and the shape pattern is provided by arraying a ferromagnetic thin film deposited on a nonmagnetic substrate surface. In addition, the MEMS relay has a suspension structure that is independent of the core. The pallet further includes a metallic support structure positioned beneath the platform structure between the upper and lower sheets and including a plurality of beam members arranged end to end in a rectangular frame configuration with each beam member generally parallel to and spaced inboard from the respective outer edge of the pallet.
