Abstract
A magnetic head supporting apparatus having a magnetic head for reading and writing information on a magnetic disc, a slider for mounting the magnetic head, and a suspension for supporting the slider. An IC chip for controlling a signal of the magnetic head is mounted on a heat insulating substrate which substantially prevents conduction of heat therethough, and the heat insulating substrate is mounted to the suspension.
Claims12
A magnetic head supporting apparatus comprising:
- a magnetic head for reading and writing information on a magnetic disc;
- a slider for mounting said magnetic head;
- and
- a suspension for supporting said slider,
- wherein an IC chip for controlling a signal of said magnetic head is mounted on a heat insulating substrate which substantially prevents conduction of heat therethrough, and said heat insulating substrate is mounted to said suspension.
2 more elements
A magnetic disc apparatus comprising:
- a plurality of magnetic discs on which information is recorded;
- a motor for rotating said magnetic discs stacked on a rotary shaft;
- magnetic heads for recoding and reproducing the information on said magnetic discs, said magnetic heads being provided so as to oppose to said magnetic discs;
- and
- a plurality of magnetic head supporting apparatus, each of said plurality of magnetic head supporting apparatus comprising an arm portion for pivotally movement, and a suspension for mounting thereon a slider for mounting said magnetic head,
- wherein said magnetic head supporting apparatus is structured such that an IC chip for controlling a signal of said magnetic head is mounted on a heat insulating substrate which substantially prevents conduction of heat therethough, and said heat insulating substrate is mounted to said suspension.
