摘要： 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.
