Suspension, head gimbal assembly and manufacturing method of head gimbal assembly

A head gimbal assembly comprising:

• a magnetic head slider with at least one thin-film magnetic head element;
• a resilient flexure made of a stainless steel, supporting said magnetic head slider;
• a load beam made of a stainless steel, supporting said flexure, for applying a predetermined load to said magnetic head slider;
• a drive IC chip with a circuit for said at least one thin-film magnetic head element;
• a lead conductor member on which said drive IC chip is mounted;
• and
• a high-thermal-conductivity member made of a material with a higher thermal conductivity than that of the stainless steel and inserted between said lead conductor member and said load beam in a region containing at least a section on which said drive IC chip is mounted.

A method of manufacturing a head gimbal assembly, comprising the steps of:

• inserting a high-thermal-conductivity member made of a material with a higher thermal conductivity than that of a stainless steel between a resilient flexure made of a stainless steel and a load beam made of a stainless steel, supporting said flexure, for applying a predetermined load to a magnetic head slider with at least one thin-film magnetic head element;
• fixing said flexure and said load beam with each other;
• mounting a drive IC chip with a circuit for said at least one thin-film magnetic head element on said flexure;
• and
• mounting said magnetic head slider on said flexure.

• inserting a high-thermal-conductivity member made of a material with a higher thermal conductivity than that of a stainless steel between a load beam made of a stainless steel, for applying a predetermined load to a magnetic head slider with at least one thin-film magnetic head element and a base plate fixed to a base section of said load beam;
• fixing said load beam and said base plate with each other;
• fixing a resilient flexure made of a stainless steel to said load beam;
• mounting a drive IC chip with a circuit for said at least one thin-film magnetic head element near said base plate;
• and
• mounting said magnetic head slider on said flexure.
