A suspension for a HGA includes a base plate, a flexure having a suspension tongue for holding a slider, a load beam, and a hinge that are assembled together; wherein a strengthening plate is formed on the suspension tongue to increase stiffness of the suspension tongue. So the invention enable the use of the suspension with lower pitch and roll stiffness while preventing the suspension deformation. This ensures the slider mounted on the suspension have a good flying performance. The invention also discloses a HGA with such a suspension and a disk drive unit having such an HGA.

A simulated gun includes a main body and a reactionary force generator having a drive force generator, an actuator and a transmitter. The drive force generator is arranged outside the main body and transmits a drive force to a core constituting the transmitter by driving of the drive force generator. The rotational arm of the actuator is rotated together with a weight about the horizontal axis by a drive force from the core, and a drive force in a direction for raising the muzzle side of the gun is imparted to the main body when the weight hammers the inner wall surface of the main body. Consequently, a specified impact force can be generated by the drive force generator arranged outside of the main body, the size and weight of the main body can be reduced, and a realistic reaction force such that the muzzle side of the gun is sprung up can be realized.

A current mirror circuit 30 comprises PMOS's 31 to 34. The current which was flowing when the input voltage was “H” is interrupted, when the node N34 goes from “L” to “H,” a cascode-connected PMOS 31 is automatically turned OFF. The gates of PMOS's 31 and 33 are connected by a signal line (SL) directly to a node N34. The rise time of the output voltage of a current mirror circuit and the consumption current can be reduced.

A signal generator circuit prevents a shift of a timing at which an output signal at high voltage level changes from a timing at which an output signal at low voltage level changes, and a level shifter prevents a through current from flowing between a high voltage power supply and a ground potential. The signal generator circuit has an output adjustor circuit for outputting a first output signal and a second output signal in accordance with an input signal, and a level shifter for converting a voltage level in accordance with the input signal to generate a third output signal and a fourth output signal. In response to a rising of the input signal, the first output signal first changes, then the third and fourth output signals change, and subsequently the first output signal changes.

A discharge accelerating unit which accelerates a discharge of a capacitive load (floating capacitor C1) of a signal line when a positive polarity input gradation voltage DAC(P) decreases is provided for a positive polarity operating circuit. A charge accelerating unit which accelerates a charge of a capacitive load (floating capacitor C2) of a signal line when a negative polarity input gradation voltage DAC(N) decreases is provided for a negative polarity operating circuit. Good characteristics can be obtained irrespective of a switching period of the positive polarity operating circuit and the negative polarity operating circuit and luminance levels of adjacent dots. The number of devices which are added by the invention can be minimized.

A method of testing a performance of the HGA has a step of writing information from the at least one thin-film magnetic head element onto a magnetic disk with driving the actuator for displacement by applying an alternating drive signal to the actuator, a step of reading out the information of at least one rotation of the magnetic disk by the at least one thin-film magnetic head element without driving the actuator for displacement, a step of storing the information read-out from the magnetic disk as a read-out information along a disk-rotating direction, a step of moving the HGA toward an off-track direction by a predetermined distance, a step of repeatedly executing the reading, storing and moving steps to obtain two-dimensional read-out information along the disk-rotating direction and the off-track direction, and a step of determining, from the two-dimensional read-out information, an off-track position where the read-out information becomes maximum at each position along the disk-rotating direction, the determined off-track positions being recognized as displaced positions of the actuator in response to the applied alternating drive signal.

A channel control apparatus is arranged in a plurality of nodes on a source as a transmission side and at a node on a sink as a reception side, and changes a bandwidth of virtual concatenation (VC) between the nodes on the source and the sink using link capacity adjustment scheme (LCAS) information. The channel control apparatus includes a VC/LCAS main controller that sets member use-request information for the VC or member usable information for the VC in the LCAS information, and changes the member of the VC between the nodes on the source and the node on the sink.
