Diskette Pressure Pad Assembly

Torsion spring 10 acting on bail 12 applies only the force on diskette assembly 14 sufficient to ensure that assembly 14 is positioned against platen 16 so that undue wear of disk 18 within its surrounding jacket 20 does not take place.

Diskette assembly 14 is of the type disclosed in U.S. Patent 3,668,658 and includes thin magnetic disk 18 rotatably disposed within surrounding jacket 20. While diskette assembly 14 is held in place against platen 16, suitable magnetic heads extend through radial slots 22 to magnetically read or write on the surface of disk 18.

Torsion spring 10 and bail 12 are carried by a disk drive cover 24 that is swingably disposed about a pivot 26. Bracket 28 is fixed to cover 24 by screws 30, and the inner end of spring 10 is fixed with respect to bracket 28 by means of tabs 32. The distance between tabs 32 is such that spring 10 is forced in place between tabs 32 so that tabs 32 provide a secure mounting for spring 10 with respect to bracket 28. Bail 12 carries pin 34 extending into U-shaped slots 36 in bracket 28 for allowing assembly of bail 12 with respect to bracket 28 and for limiting the motion of bail 12 by pin 34, which contacts the ends 36a of slots 36 when cover 24 is swung open in direction A.

Spring 10 acts against bail 12, forcing bail 12 against diskette assembly 14 in position on platen 16, and provides a relatively uniform force on diskette assembly 14, as cover 24 is swung into its illustrate...
