Abstract: An apparatus includes a receiving area configured to receive a plurality of mounts,each mount being configured to support at least one tape spool pair thereon. A magnetic head is configured to perform data operations on magnetic recording tapes of the tape spool pairs. A positioning mechanism is configured to selectively align the magnetic head to a selected one of the tape spool pairs. A product apparatus, in accordance with another approach, includes a mount having a tape spool pair thereon.The mount is configured to be insertaed in a receiving area of an apparatus configured to receive a plurality of mounts.

Abstract: A TAPE MOVEMENT CONSTRAINT IS PROVIDED FOR A TAPE DRIVE SYSTEM WHICH MOVES A TAPE LONGITUDINALLY ALONG A TAPE PATH ACCROSS A TAPE HEAD, THE TAPE HAVING LONGITUDINAL TRACKS. THE TAPE HEAD HAS A TRACK FOLLOWING SERVO SYSTEM FOR MOVINGTHE HEAD LATERALLY FOR FOLLOWING LATERAL MOVEMENT OF THE TRACKS, WHERE THE TAPE IS SUBJECT TO LATERAL TRANSIENT MOVEMENT. A TAPE ROLLER BEARING CLOSELY ADJACENT THE TAPE HEAD IS ROTATABLE ABOUT A CENTRAL AXIS PARALLEL TO THE CYLINDRICAL PERIPHERAL SURFACE, ALLOWING THE TAPE FREEDOM OF MOVEMENT IN THE LONGITUDINAL DIRECTION. THE TAPE ROLLER BEARING HAS A FRICTIONAL CYLINDRICAL PERIPHERAL SURFACE FOR CONTACTING AND ENGAGING THE SURFACE OF THE TAPE AND CONSTRAINING MOVEMENT OF THE TAPE IN THE LATERAL DIRECTION, THEREBY REDUCING THE RATE OF THE LATERLA TRANSIENT MOVEMENT OF THE TAPE TO ALLOW THE TRACK FOLLOWING SERVO SYSTEM TO FOLLOW THE REDUCED RATE LATERAL TRANSIENT MOVEMENT OF THE LONGITUDINALTRACKS. ANY POTENTIAL AIR BEARING THAT COULD FORM BETWEEN THE SURFACE OF THE ROLLER BEARING IS COLLAPSED TO INSURE THAT THE ROLLER BEARING FRICTIONALLY CONTACTS AND ENGAGES THE SURFACE OF THE TAPE.

Abstract: AN OPTICAL DISK RECORDER, OR OTHER APPARATUS, USE A ROTARY ACTUATOR FOR SUPPORTING A WORK TOOL, SUCH AS AN OBJECTIVE LENS WHICH IS PIVOTABLE OR ROTATABLE ABOUT A PIVOT PIN. ROTATION CAUSING OR TRACKING COILS ON THE ROTARY ACTUATOR ARE DISPOSED ADJACENT TO PERMANENT MAGNET TO SELECTIVELY EFFECT ROTATION OF THE ROTARY ACTUATOR ABOUT THE PIVOT PIN. A BIAS ELECTRICAL CURRENT IS SUPPLIED TO THESE COILS TO GENERATE MAGNETIC FIELDS WHICH ARE IN OPPOSITE ROTATIONAL SENSES; SUCH FIELDS FORCE THE ROTARY ACTUATOR AGAINST THE PIN IN SUCH A MANNER THAT THE POINT OF CONTACT BETWEEN THE ROTARY ACTUATOR AND THE PIN FOLLOWS THE ROTATION OF THE ACTUATOR ABOUT THE PIN.
