Latest Patents
One of his latest patents is for a high-speed bidirectional magnetic tape transport with constant tension. This invention involves a length of magnetic tape extending between a pair of reels within a cartridge, driven bidirectionally at high speeds while maintaining substantially constant tension. The transport utilizes a pair of capstans that engage and move to accommodate the constantly changing tape packs on the reels. Constant tape tension is achieved through a driving arrangement that employs pairs of pulleys of slightly different diameters, coupled via overriding unidirectional clutches to shafts that mount the capstans. These shafts are driven from a common motor by belts connected to the different pairs of pulleys. The difference in pulley diameter ensures that the capstan engaging the takeup reel is driven slightly faster than the capstan engaging the supply reel, thus maintaining constant tape tension. The tape cartridge features a single front door that automatically raises upon insertion into the transport, along with spring-loaded arrangements that block rotation of the reels except when the cartridge is inserted. Additionally, dust covers are movable out of the way by the movement of the capstan shafts into slots in the cartridge. A camming arrangement engages the bottom of the cartridge to ensure proper alignment with three different height referencing elements, while a separate locking arrangement secures the cartridge in a desired horizontal position until released.
