PURPOSE:To simplify the constitution of a magnetic head device so as to make manufacturing of the magnetic head device easier, by fitting a multichannel magnetic head and its related IC chip to a printed circuit board and then putting them in a housing as one body. CONSTITUTION:The electrode of a condenser array 16 is soldered onto, for instance, a prescribed conductor layer on the same plane of a board 23 and, at the same time, an IC chip 18 is connected with another prescribed conductor layer by wire bonding. Then the lead conductor layer 23a of such board 23 is soldered to each terminal of a multichannel MR head 15 which is previously fitted to a mold body 21. Thereafter, the board 23, to which each of the above-mentioned parts is fitted, is placed on the mold body 21, in which a heat sink 19' provided with an internal thread for fitting 19a' is buried, and they are united in one body by molding on the board 23 with a potting resin 22'. Therefore, the reliability and strength of the magnetic head device thus manufactured can be secured. |
