To provide a disk drive system provided with an inertial latching mechanism which has high reliability and can be arranged in a thin-model disk drive system. There is provided an inertial arm (7) engaging an actuator (22) when a head arm (25) is in or near a parking position and releasing engagement with the actuator (22) when the head arm (25) is in or near a position close to a disk (1) and energizing means for holding a position of the inertial arm (7) in a position where the engagement with the actuator (22) is released. Even if a rotational shock is externally applied when the actuator (22) remains in the parking position, moment of rotation is applied on each of the actuator (22) and inertial arm (7) in the same direction, the actuator (22) and inertial arm (7) mutually restrain their operations at an engaging part, and the oscillation of the actuator (22) to a data area can be avoided. When loading, a position of the inertial arm (7) is held by the energizing means in the position where the engagement with the actuator (22) is released so that the release of the engagement and mode of operation of the engagement between the actuator (22) and inertial arm (7) when loading/unloading can be surely achieved.

The present invention obtains both the feature of deodorizing by means of active species and the feature of killing floating and attached bacteria by releasing the active species to the exterior of a device. The present invention is provided with a pair of electrodes (21, 22), electrode (21) being arranged with the dielectric film (21a) on the surface facing electrode (22) and electrode (22) being arranged with dielectric film (22a) on the surface facing electrode (21), wherein plasma is discharged when a predetermined voltage is applied between the electrodes (21, 22). The present invention is configured in a manner such that a fluid through-hole (21b, 22b) is disposed on and through each electrode (21, 22) on a corresponding location, and is characterized in that at least a portion of the outline of the corresponding fluid through-holes (21b, 22b) are positioned at a different position from one another when viewing from face plate direction of the electrodes.

There are provided a recording head capable of reduction of variations in heat-generating temperature among heat-generating elements constituting a heat-generating-element array, and a recording device including the recording head. A recording head includes a heat radiator; a head base body having a substrate placed on or above the heat radiator and a heat-generating-element array composed of a plurality of heat-generating elements arranged on or above the substrate; a bonding layer that is interposed between the heat radiator and the substrate and bonds the heat radiator with the substrate; and a plurality of spacer particles arranged within the bonding layer so as to abut on both of the heat radiator and the substrate. The bonding layer includes a first region situated immediately below the heat-generating-element array and a second region extending in parallel with the first region. The spacer particles are arranged in the second region.

An information-recording method includes the steps of moving a light beam at a selected linear velocity relative to the information-recording medium; controlling the light beam to generate a multi-pulse having at least three power levels of a first power level Ph, a second power level Pl which is lower than the first power level, and a third power level Pm which is intermediate therebetween, the multi-pulse being repeatedly modulated between the first power level Ph and the third power level Pm; adjusting the third power level Pm in response to the selected linear velocity; and recording the information by irradiating the information-recording medium with the controlled light beam. Recording compatibility can be secured for information-recording apparatuses different in recording linear velocity and laser source characteristic.
