There is disclosed a magnetic head device in which a head IC chip may be located relatively closer to a magnetic head and a thermal effect may be controlled to be within a range of acceptable degree. Said magnetic head device comprises a head slider having a magnetic head, a suspension member which is made of thin resilient material and supports the head slider at one end thereof, and a head IC chip, wherein the suspension member is attached to other member at the other end thereof. The IC chip is mounted on the suspension member. When the IC chip is selected to have appropriate disc side area and is mounted on the suspension member, the temperature of the IC chip itself may be maintained within a range of acceptable degree and that of the magnetic head may be also kept to be lower. When the electric power consumption of the IC chip is equal to or less than 410 mW, the disc side area thereof should be equal to or more than 1.1 mm2. The IC chip is mounted on a surface of the suspension member at a side facing to the disc at a position where a relative linear velocity equal to or more than 25 m/sec is generated with respect to said disc.

A suspension includes a resilient flexure for supporting a magnetic head slider near its one end, and a load beam with a base end portion, for supporting the flexure. Particularly, connection conductors are formed on the flexure in a thin film pattern, and one ends of the connection conductors are to be connected to the magnetic head slider and the other ends of the connection conductors are positioned near the other end of the flexure. The other end of the flexure extends to at least a position of the base end portion of the load beam.

A magnetic head apparatus includes a slider with at least one magnetic head element, a suspension having one end portion, one surface and the other surface opposite to the one surface, for supporting the slider at the one end portion, a head IC chip mounted on the one surface of the suspension, and an air-cooled radiator member fixed on the other surface of the suspension.
摘要:
A method of fabricating a magnetic head device comprising a slider having a magnetic head element, a suspension structure made of a thin resilient material and having one end supporting the slider and the other end to be attached to another member, and a head IC chip. The head IC chip is mounted on the suspension structure so as to face a magnetic recording disc and at a position spaced from the slider-supporting one end of the suspension structure by an intervening portion of the suspension structure. The position is selected so that the intervening portion is effective to suppress a temperature increase in the head IC chip due to at least thermal conduction through the intervening portion.
