Abstract

The diskette drive shown above is designed to receive a rigid cartridge 8 containing a floppy disk 17. The cartridge is position registered in the drive, and thereafter the floppy disk is centered and clamped by collet 14. To insure proper centering of the floppy disk on the spindle 16, the disk is centered and clamped by collet 14 onto spindle 16 before the recording head pressure pad and the disk cleaning pad are brought into contact with the disk. The sequential operations of clamping the disk, lowering the pressure pad and raising the disk cleaning pad are all accomplished by the operator moving handle 11 and thus lever 12 from left to right after the cartridge has been inserted. drive.

Centering and Clamping a Floppy Disk in a Diskette Drive

The diskette drive shown above is designed to receive a rigid cartridge 8 containing a floppy disk 17. The cartridge is position registered in the drive, and thereafter the floppy disk is centered and clamped by collet 14. To insure proper centering of the floppy disk on the spindle 16, the disk is centered and clamped by collet 14 onto spindle 16 before the recording head pressure pad and the disk cleaning pad are brought into contact with the disk. The sequential operations of clamping the disk, lowering the pressure pad and raising the disk cleaning pad are all accomplished by the operator moving handle 11 and thus lever 12 from left to right after the cartridge has been inserted. drive. At the same time that the cartridge registration holes slip over the registration pins in the diskette drive, the spindle hole 44 in the diskette cartridge slips over the spindle 16. The slight pressure provided by the spring fingers 40 causes the cartridge to drop down in proper position over the conical pins and spindle.

When cartridge 8 is registered, lever 12 is moved to the right, pressing leaf spring 34 down. Collet 14, carried by leaf spring 34, moves down through the center of disk 17 and clamps disk 17 to spindle 16.

After collet 14 has centered the disk 17 on spindle 16, extension 38 of lever 12 moves away from spring-loaded pin 36. Pin 36 rotates pressure pad arm 32 down and thus lowers a pressure pad on the e...
