Abstract

Shown above is a head carriage assembly for single-sided or double- sided recording of a floppy disk within a rigid cartridge. One head is mounted rigidly to the base of the cartridge, while a second head or a backing pad for the first head is mounted on a swing arm. The swing arm contains a bend in the plane of its swing arm motion. When the swing arm is rotated up for insertion or removal of the diskette, the bend in the arm allows the arm and its head or backing pad to clear the thick, rigid cartridge being loaded or unloaded from the drive. In the above drawing, carriage 10 rides on rails 12 that pass through guides 14 molded into the carriage. Recording head 16 is rigidly mounted to carriage 10. A second recording head 18 or, alternatively, a backing pad is mounted at the end of swing arm 20.

Head Carriage Assembly for Thick Rigid Diskettes

Shown above is a head carriage assembly for single-sided or double- sided recording of a floppy disk within a rigid cartridge. One head is mounted rigidly to the base of the cartridge, while a second head or a backing pad for the first head is mounted on a swing arm. The swing arm contains a bend in the plane of its swing arm motion. When the swing arm is rotated up for insertion or removal of the diskette, the bend in the arm allows the arm and its head or backing pad to clear the thick, rigid cartridge being loaded or unloaded from the drive. In the above drawing, carriage 10 rides on rails 12 that pass through guides 14 molded into the carriage. Recording head 16 is rigidly mounted to carriage 10. A second recording head 18 or, alternatively, a backing pad is mounted at the end of swing arm 20. Arm 20 is normally biased downward by spring 22 so that recording head 18 is positioned opposite recording head 16. To insert a rigid cartridge containing a floppy disk between the two heads, swing arm 20 must be rotated upwards. A bail (not shown) engages finger 24 to lift arm 20 upwards. Because arm 20 is bent at portion 26 of its length, a wide separation between heads 16 and 18 is achieved when arm 20 is rotated upwards. This wide separation allows for the insertion of the relatively thick, hard cartridge containing the floppy disk.
