Band Access

A carriage for moving a recording head in a flexible disk drive is shown above in top and side views. The carriage is moved by a band drive clamped to a drive pulley. This drive assembly may be put together as an integral assembly and adjusted before being placed in the disk drive.

Band 1 is mounted on a pin on pulley 2, wrapped clockwise until it goes toward idler pulley 3, wrapped around the idler, and brought back to pulley 2 and mounted on the same pin in the pulley. The band is then clamped to the pulley with clamp 4. Idler assembly 5 is then spring loaded in the direction indicated to tension the band for operation. The access driving system can then be set to a predetermined phase of the access stepper motor, and pulley 2 can be tightened to the shaft of stepper motor 7. The carriage drive system is now an integral assembly that allows removal or insertion of the carriage without disturbing the band, pulley, or idler.

To adjust the position of carriage 6, stepper motor 7 is energized to move the head to a predetermined track position. Feeler gage 8 is inserted between surfaces A and B, and both surfaces are brought in contact with the feeler gage. The carriage can then be clamped to the band, completing the adjustment.
