Air Bearing

An air bearing for a magnetic tape drive can include a foil face that is wrapped over a bearing block having the desired radius. One end of the foil has a registration hole that is placed over a pin for alignment. The other end of the foil includes a tensioning mechanism to pull the foil taut over the face of the bearing block.

As shown in the figure, a bearing block 1 includes an air hole 2 that leads to a channel across the face 3 of the bearing block 1.

The air channel directs the air from internal inlets across the entire face for distributing the air through holes 4 in the foil 5.

The bearing block 1 also includes a registration pin 6 for matching with hole 7 in the foil 5. A tensioning device 8 is connected to one end of the foil 5. The tensioning device fits into cutout 9 in the bearing block 1. A screw 10 is used in a threaded hole 11 to lock the tensioning device 8. A screw 12 and a washer 13 hold the registration end of the foil 5 in place.

To assemble the air bearing guide of the figure, the hole 7 of the foil 5 is placed over the pin 6. The screw 12 passes though washer 13 and an opening 14 in the foil 5 for positively connecting the end of the foil to the guide block 1. The foil is then formed across the face 3 of the block 1, and the tensioning device 8 is placed into cutout 9. The tensioning device 8 includes a slot into which a screwdriver is inserted to twist the tensioning device in order to pull the foil taut over the face 3 of the...
