Diskette Marking

Characters permanently identify manufacturing information directly on a magnetic diskette. Preferably, the identification should be made automatically during a final manufacturing step.

In Fig. 1, the identification 500 may appear adjacent to central drive hole 24 of magnetic disk 20 (shown mounted in jacket 22).

In Fig. 2, a web of magnetic media passes through an accumulator column, which assists in maintaining a constant feed rate and tension, a hot stamp station, a punch press and feed rollers to a take-up roll. Progressive die in the punch blanks out disks 20 from the web, the scrap media being wound onto a scrap reel.

The hot stamp imprints the desired identification on the magnetic media web simultaneously with the blanking of an adjacent disk. If desired, additional information may be conveyed by the position of the stamped identification relative to the hole (Fig. 1), or by selecting one side of the disk or the other for identification, etc.
