Portable Rigid Disk Handling Device

A portable rigid disk handling device is structured to contact a disk for incorporation into disk drive only on the uncoated inner band area. The disk handling device 10 generates its own 2-pound lifting force and has a housing 20 which is a press fit over element 25, see drawing.

There are eight air holes 30, equally spaced around a circumference of element 25, leading to the air chamber 35. Housing "O" rings 40 are seated in circular grooves 41 and 42 and create the seal between element 25 and disk 50. A plunger 60 slides freely up and down within the housing 20 and contains "O" ring seals 65.

To operate, plunger 60 is pushed down by light hand pres sure. This compresses spring 70 and expels most of the air from air chamber 25. The device 10 is then placed on disk 50 as in the drawing (the disk is usually on a spindle which locates the device onto the disk), and plunger 60 is released. Compression spring 70 forces the airtight plunger 60 slightly upward, creating a vacuum force capable of lifting and holding the disk To release the disk 50, the plunger 60 is again pushed down.
