Floppy disk drive unit with mounting plate between carriage and lower magnetic head

摘要

The height of the lower head is equal to that of the upper heads. A mounting plate is provided between the lower head and a carriage to provide penetration arrangement. The lower head is fixed on the carriage through the mounting plate with adhesive. The mounting plate has a rough area having small holes to provide surely adhering with accuracy. The thickness of the mounting plate is accurate because of punching (cutting) processing and is greater than that of the shutter. The width of the mounting plate is greater than that of the lower head but smaller than the shutter opening of the floppy cartridge to avoid influence to the motion of access of the magnetic head to the floppy disk. The gimbal plate for the lower magnetic head is omitted, so that the orientation of said lower magnetic head is fixed.
