Abstract

The read/write head support structure shown in the figures illustrates a compound cantilever design which permits the parallel translation of the head to eliminate roll. The support includes a pair of primary cantilevered legs 5 that are fixedly secured at one end to a supporting base or frame 6. The read/write head 7 is supported at the ends of secondary cantilevered legs 8 that are connected to the primary cantilevered legs by a cross leg 9. The transfer lengths l0 of cross leg 9 are the portions between adjoining primary and secondary legs which are placed in torsion when the head moves away from a neutral position as a result of action by either a load arm urging the head toward the disk or the force of the disk in the opposite direction.

Complementary Cantilever Flexible Disk Head Suspension

The read/write head support structure shown in the figures illustrates a compound cantilever design which permits the parallel translation of the head to eliminate roll. The support includes a pair of primary cantilevered legs 5 that are fixedly secured at one end to a supporting base or frame 6. The read/write head 7 is supported at the ends of secondary cantilevered legs 8 that are connected to the primary cantilevered legs by a cross leg 9. The transfer lengths l0 of cross leg 9 are the portions between adjoining primary and secondary legs which are placed in torsion when the head moves away from a neutral position as a result of action by either a load arm urging the head toward the disk or the force of the disk in the opposite direction.

The parallel translation is shown in Fig. 2, wherein A shows the neutral, unstressed position of the support, B shows an upper position that occurs when the disk forces the head up with a greater force than applied by the load beam, and C shows a downward position obtained when the disk exerts a smaller force than the load beam. The parallel translation or zero roll condition is obtained by the selection of the shape, length, width and thickness of the primary, secondary and transfer legs of the support.
