摘要： PROBLEM TO BE SOLVED: To provide an inexpensive magnetic head apparatus which can accurately perform reproduction operation at a high transfer rate even when a track pitch is narrow.
SOLUTION: A head chip of a recording head 10 is a multi-recording head constituted by integrating two(=m) groups of multi-head each composed of four magnetic heads by a thin film technology so that magnetic signals are reproduced simultaneously from eight recording tracks in each of which recording is performed with a prescribed track pitch. Each of first group magnetic heads H11 to H14 is constituted such that each head width is equal to a track pitch Tp of a recording track formed in a magnetic tape 2, and among the heads H11 to H14, the heads adjacent to one another are arranged so as to be deviated in the longitudinal direction of the recording track. Also, these two groups of multi-heads are adjacent to each other on the head chip of the reproducing head 10, and arranged so as to be deviated by a distance D determined by an expression D=Tp×q×(m×n+1)=12T.

摘要： PROBLEM TO BE SOLVED: To provide a magnetic head device capable of being surely adhered to an actuator and preventing the overflow of an adhesive material used for adhesion.
SOLUTION: Adhesion parts 2a and 2b are recessed groove parts having planar adhesion surfaces 2a2 and 2b2 over the entire height direction of a slider 1 and slopes 2a1 and 2b1 whose slope width is equal to an adhesion part width WS forming an angle θk with a horizontal plane on the base part side (X1 direction side) of a microactuator. Thus, a space where the adhesive material used for the adhesion can enter is increased by the portion of the adhesion part width WS and the adhesive material is prevented from overflowing to the ABS surface 1d of the slider 1. Also, since the adhesive material is blocked by the slopes 2a1 and 2b1, the adhesive material is surely prevented from overflowing to a free area.
