摘要： Magnetic tape (13) on a supply reel (11) is provided with a trailing end leader (27) which has an abrasive cleaning characteristic. In order to effectively use the leader with the cleaning characteristic, the tape is fully unreeled to expose the abrasive leader (27) only when a requirement to clean the tape head transducers is sensed. During normal operation, the trailing leader (25) which includes the cleaning leader (27) is not exposed to the tape transducer head, but instead remains on the supply reel.

摘要： A read-only memory device is described having non-volatile memory cells that include a memory component connected between electrically conductive traces. A memory component is formed to include a resistor that indicates a resistance value when a potential is applied to a selected memory cell. The resistance value of a memory component in an individual memory cell corresponds to multiple logical bits. The resistance value of a memory component corresponding to a set of logical bits can be based on a thickness and/or an area of electrically resistive material that forms the memory component, and/or based on the geometric shape of the memory component, where different geometric shapes of the electrically resistive material have different resistance values that correspond to different sets of logical bits.

摘要： An inexpensive, vertically oriented multiple substrate carrier is disclosed for high-temperature, high vacuum film deposition systems. In one embodiment, the substrates have central circular openings and the carrier includes a plurality of supports on which the substrates hang, with each support, such as a vertically oriented sheave, engaging the perimeter of a substrate opening. As the carrier is rotated, planetary motion is imparted to the substrates to facilitate simultaneous, two-sided, substantially uniform deposition of a film. In another embodiment, the substrates are circular and are each supported for planetary motion and two sided deposition in a respective circular groove which bounds an opening through the carrier.

摘要： A sealed substrate processing path has plural selectably isolatable vacuum deposition chambers along the path. A transporter carries substrates along the path and an independently controllable sputter deposition is performed in each deposition chamber on substrates therein. Substrates are loaded from a load chamber to a first deposition chamber while a vacuum is maintained in the first and load chambers. Substrates are transferred from a last deposition chamber to an unload chamber while a vacuum is maintained in the last and load chambers. Substrates are placed in the load chamber while the load and first chambers are isolated and are removed from the unload chamber while the last and unload chambers are isolated. In one embodiment, substrates travel succesively from the load chamber to first through fourth deposition chambers and then to the unload chamber. In another embodiment, substrates travel from the load chamber to first to second to first and to third deposition chambers and then to the unload chamber. First and second alternating load chambers are provided in another embodiment with substrates being loaded into the second load chamber while substrates are transferred from the first load chamber to the first deposition chamber and vice versa. The respective first and second load chambers are coupled through an interface chamber to the first deposition chamber and are each isolatable from the interface chamber during loading.
