Latest Patents

One of Harper's latest patents is titled "Magnetically biased tilting roller bearing tape guidance." This invention provides a tape movement constraint for a tape drive system. It comprises a tiltable tape roller bearing with a grooved surface designed to contact and engage the tape as the roller barrel rotates. An actuator is included to pivot the roller bearing surface, allowing for precise control of the tape's lateral position. In operation, the roller barrel is biased in a first position on a pivot axis using magnetic attraction between a movable magnet and a return path structure made of magnetically permeable material. The roller barrel pivots on the pivot axis by conducting current through a fixed coil, generating a magnetic field that interacts with the magnetic field of the magnet. Other embodiments of this invention are also described and claimed.
