    • 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.
    • 公开了一种磁头装置,其中头部IC芯片可以相对靠近磁头定位,并且可以将热效应控制在可接受的程度的范围内。 所述磁头装置包括具有磁头的磁头滑动器,由薄弹性材料制成的悬架构件,并在其一端支撑磁头滑块,以及磁头IC芯片,其中所述悬挂构件在所述磁头滑块 的另一端。 IC芯片安装在悬挂构件上。 当IC芯片被选择为具有适当的盘侧面积并安装在悬挂构件上时,IC芯片本身的温度可以保持在可接受的程度的范围内,并且磁头的温度也可以保持较低。 当IC芯片的电力消耗等于或小于410mW时,其盘侧面积应等于或大于1.1mm 2。 IC芯片在相对于所述盘产生相对线速度等于或大于25m / sec的位置处,在面对盘的一侧安装在悬挂构件的表面上。
