A pallet main body is provided with a block holding member which presses a positioning surface of an actuator block against a block reference surface formed in the pallet main body, and a movable arm. An insertion member, which can be inserted between a plurality of opposing suspensions, is formed at a distal end of the movable arm. As a suspension to which a slider is to be attached contacts a first contact surface formed on the side in contact with this suspension, a distal end of the suspension to which the slider is to be attached is held at a prescribed height from the block reference surface, thereby forming a gap between this suspension and a suspension opposed to this suspension.

A method of manufacturing a magnetic head, and a magnetic head manufacturing apparatus, are provided, which make it possible to post mount a slider to a suspension even when the suspension and an actuator block are assembled together in advance, thus preventing the slider from being destroyed due to ESD or the like. First, a plurality of opposing suspensions are pushed open, forming a gap having a prescribed height between distal ends of the suspensions to which the slider is to be attached. Both side surfaces of the slider are then gripped by pressing surfaces formed on a gripping mechanism. An ABS of the slider is made to contact a horizontal regulating surface formed on the gripping mechanism, thus regulating the horizontal attitude of the slider. The slider, which is gripped by the gripping mechanism, is then inserted into the gap. A rear surface of the slider is attached to the distal end of the suspension through a connecting member.

A fluorescent print head driving method is provided wherein an operational lifetime is improved by reducing the evaporation amount of Ba contained in an electron emitter material of a filament cathode and suppressing the deterioration of the luminous efficiency. In the pre-luminous period T1 during which luminous dots glow before forming an image on a recording medium, a grid voltage is controlled to be a predetermined voltage of a rated value or less and a filament voltage is controlled to a predetermined voltage of a rated value or less. In the print luminous period T2 during which luminous dots glow before forming an image on a recording medium, a grid voltage blank period is created corresponding to a luminous blank period between glow states during which an anode voltage is written for one line on the recording medium. The anode voltage and the grid voltage are controlled to be a rated voltage with a duty ratio corresponding to a blank period. Thus, the filament voltage is controlled to be a predetermined voltage of a rated value or less.
