ABSTRACT:
A computer diskette burnishing machine that consists of two burnishing units adapted to operate on the magnetic medium of a conventional computer disk through the upper and lower read/write head access windows in the disk's protective shell. The assembled diskette is positioned on a lower burnishing unit that comprises a supporting plate having the same mechanical characteristics of a corresponding computer disk drive, including an electric motor equipped with a spindle/hub interface and shell registration pins. While the disk rotates, the burnishing units polish the disk's upper and lower surfaces by means of upper and lower abrasive tapes fed by a system of supply and take-up reels. The lower burnishing unit includes a resilient roller backing up the lower abrasive tape and disposed radially with respect to the plane of the disk. The upper burnishing unit consists of a spring-loaded resilient roller backing up the upper abrasive tape and disposed radially in parallel to the lower roller. The upper roller is supported by a spring-loaded mechanism that ensures a preset constant force against the disk when brought to press against it. Both upper and lower units are slidably mounted on a vertical slide and driven by a cam mechanism for cyclical vertical motion between burnishing steps. The cam mechanism is also used for moving disks sequentially into a working position, for opening the disk shutter prior to burnishing, and for removing polished disks.
