Abstract

The dual-sided buffer illustrated uses a pair of buff tapes having a width which slightly exceeds the operational width of the magnetic coating 3 of the rigid data disk 4 being processed. The device includes an upper buff tape 5 that runs from a supply spool 6 to a take- up spool 7 and a lower buff tape 9 that extends from supply spool 10 to take-up spool 11. Each of the buff tapes is wetted with a buffing fluid in the form of mineral oil supplied from reservoir 13 by the slotted transfer rolls l5 and l6. The buff tapes 5 and 9 are maintained in contact with disk 4 during the buffing procedure by a pair of buffing rolls l9 and 20, respectively. The buff rolls 19, 20 are each carried on a linear ball slide 22 that is driven into and out of an operative position by an air cylinder 23.

Double-Sided Rigid Disk Buffer

The dual-sided buffer illustrated uses a pair of buff tapes having a width which slightly exceeds the operational width of the magnetic coating 3 of the rigid data disk 4 being processed. The device includes an upper buff tape 5 that runs from a supply spool 6 to a take- up spool 7 and a lower buff tape 9 that extends from supply spool 10 to take-up spool 11. Each of the buff tapes is wetted with a buffing fluid in the form of mineral oil supplied from reservoir 13 by the slotted transfer rolls l5 and l6. The buff tapes 5 and 9 are maintained in contact with disk 4 during the buffing procedure by a pair of buffing rolls l9 and 20, respectively. The buff rolls 19, 20 are each carried on a linear ball slide 22 that is driven into and out of an operative position by an air cylinder 23. The linear ball slides 22 are secured to the mounting wall 25 and slightly canted by shims 27 to create a tilt angle. The tilt angle of a value less than 1 degree provides the ramp or radial outward taper of the coating surface, as required, for the disk being buffed.

In operation, the buff tapes continuously buff the entire utilized width of the magnetic coated surface, producing a more uniform buffed coating thickness, an improved ramp linearity, and a shorter buffing cycle than the current double-sided buffers.
