A planar illumination unit includes an optical guide layer for guiding light therethrough and emitting the light from a top surface, a light source fixture provided so as to face a side wall of the optical guide layer for injecting a light into the optical guide layer, an optical scattering layer disposed above the top surface of the optical guide layer for causing a scattering in the light that has been received from the optical guide layer, and a reflector provided on a bottom surface of the optical guide layer for reflecting the light incident to the optical guide layer, wherein the light source fixture includes a reflector for reflecting the light that has been produced by a light source in a direction primarily offset from the light source.

A flexible magnetic diskette used for magnetically storing various information which is recorded and read by a magnetic head. The diskette includes a flexible plastic disk sheet uniformly coated with magnetic material and having a mount hole at its center, and a holder for securing the disk sheet over the periphery of the mount hole. The holder is also made of a plastic material for holding the flexible disk sheet over the peripheral portion of the mount hole via a double-sided adhesive ring. A core member is made of a magnetic metal having a high abrasive resistance and rigidly attached to the holder over at least a part of a surface of the holder, with which a drive unit is engaged.
