摘要： A carriage for a disc device, which has a top arm, bottom arm, and mid arm, has a main mode, end arm mode, and mid arm mode as a frequency response obtained when subjected to a vertical shake. In the main mode, all of the top, bottom, and mid arms swing at a first frequency within the same phase in a primary bending mode. In an end arm mode, the top and bottom arms swing at a second frequency higher than the first frequency within opposite phases and with an amplitude larger than that of the mid arm. In the mid arm mode, the mid arm swings at a third frequency having a difference of 50 Hz or less from the second frequency within the same phase as in the main mode, and the top and bottom arms swing within the phase opposite from that in the main mode.

摘要： A suspension for disc drive comprises a load beam fitted with a flexure, an actuator base including a base plate, a hinge member thinner than the base plate, and a pair of piezoelectric ceramic elements. The piezoelectric ceramic elements displace the distal end portion of the load beam in a sway direction when supplied with voltage. Each piezoelectric ceramic element is stored in an opening portion in the actuator base. A covering material such as an adhesive agent that fills the space between the peripheral edge portion of the piezoelectric ceramic element and the actuator base forms a cover portion that covers the opposite end faces and the opposite side faces of the ceramic element.

摘要： A disc drive apparatus has a base, a disc, and a carriage. The base has a first vibration mode and a second vibration mode as reference vibration modes with respect to frequency response characteristics observed when the disc drive apparatus is shaken. The second vibration mode has a low-frequency second vibration mode (Base 2nd-1), in which a waveform peak is created on the low-frequency side, and a high-frequency second vibration mode (Base 2nd-2), in which a waveform peak is created on the high-frequency side. The two second vibration modes (Base 2nd-1 and Base 2nd-2) have a relationship such that the phase of a pivot position is inverted between them. A frequency of a first bending mode of an arm of the carriage is set in a frequency domain in a trough between the two second vibration modes.

摘要： A head suspension restricts deformation of a flexure caused by frictional force produced between a hard disk and a slider when the hard disk turns in a reverse direction. The head suspension has a load beam resiliently supported with a base. The base is supported with an arm that is turned around an axis. The load beam applies load onto a head having a slider to write and read data to and from the hard disk. The flexure is attached to the load beam and has a tongue that supports the slider. The flexure is provided with a limiter that limits displacement of the tongue due to frictional force produced between the hard disk and the slider when the hard disk is reversely turned. The limiter is on the base side and faces a free end of the tongue. The limiter is integrally formed from a part of the flexure, to face the free end of the tongue.
