Abstract: PROBLEM TO BE SOLVED: To provide a tape head designed for transducing data on a magnetic recording tape that is subjected to tape dimensional changes.
SOLUTION: The tape head includes two or more arrays of transducer elements having different transducer spacing distances corresponding to different track spacing distances to be transduced. One of the transducer arrays can be used for transducing the tape under nominal tape track spacing conditions. Another transducer array can be used for transducing the tape when the tape track spacing is reduced due to the tape shrinkage. Still another transducer can be used for transducing the tape when the tape track spacing is enlarged due to tape expansion.

Abstract: PROBLEM TO BE SOLVED: To provide an optical data storage system with which even data from any data layer of an optical medium consisting of plural data is clearly read. SOLUTION: The optical data storage system suitable to a large capacity of storage is composed of the optical medium having a multiple data surface and a driving device including an optical head. A desired data surface is irradiated with laser beams and reflected light is used as a signal by the driving device. When data in a deep data layer is read, since light has to pass through many layers, a weak signal only is obtained. Consequently, signal intensity is difference depending on the data surface. Respective data surface is optimized so that the signal intensity from each data surface becomes nearly equal by using the medium having a coated dielectric reflecting layer and by suitably selecting the coating material and its thickness. In the preferable embodiment, semiconductor material is stuck onto each data surface and the reflecting quantity is decided by the thickness.

Abstract: PROBLEM TO BE SOLVED: To reduce a vibration mode and enhance performance and stability by a method wherein there are formed an outside coil and a concentric inside coil in a backward extension part, and at the time of selection, a current of the inside coil is in a counter direction to a current of the outside coil during setting operation and tracking operation, and a current of the outside coil and the inside coil is in the same direction during seek operation. SOLUTION: A double coil actuator assembly 100 has outside and inside actuator coils 102, 104 between actuator coil support arms 94, 96 backwardly of a main body 92. Currents IO, II of the coils 102, 104 during seek operation are in the same direction, and a magnetic field generated by the currents IO, II generates a large synthetic torque by an interaction with the magnetic field of a VCM magnet. In the case of setting operation and tracking operation, the currents IO, II is in a counter direction to each other, and by the interaction with the VCM magnet, an excitation of a vibration mode due to a force generated by the coils 102, 104 is cancelled.

Abstract: PROBLEM TO BE SOLVED: To enable a band operation highly by providing sensing means forming the signals correlated to a vibration mode in an actuator, inducing correction adjusting signals from these signals and combining the adjusting signals and a position signal and feeding back them to the actuator to avoid the limitation of a gain filtering. SOLUTION: A position sensor 36 or a read/write head is connected to a digital servo 40 and the operation of an actuator 26 is limited based on the position of the read/write head. Sensors 32, 34 are connected to an active actuator control 44 via a filter 46 being an arbitrary selection and an acceleration interrupting circuit 48 being an arbitrary selection. The actuator control 44 has a stiffening part 54, an active control part 56 and an inertia reducing part 58 and it induces a stiffening correction, an active braking correction and an inertia reducing correction from signals 52 and these adjustment signals 60 are transmitted to a coupler or an adder 62 to be connected to the digital servo 40.

Abstract: An actuator assembly having two coils disposed between the poles of a voice coil motor (VCM) magnet for improved dynamic performance during settling and tracking operations in a disk drive. The two coils in the VCM are connected to separate current sources to allow the current flow in the two coils to have the same sense (clockwise or counterclockwise) or the opposite sense with respect to each other. When the current flows in the two coils have the opposite sense, excitation of the principal in-plane bending mode resonance of the actuator assembly is suppressed allowing the use of an increased servo bandwidth for settling and tracking operations of the disk drive. During seek operations of the disk drive, where maximum torque on the actuator is desirable, the coil currents in the two coils are chosen to have the same sense so that the forces on the actuator from the two coils are additive.
