Abstract
To strengthen a flying lead portion of a long-tail flexible printed circuit (FPC) integrally formed with a flexure, stacked support portions of resin layers on both sides of a flying lead 7 of a long-tail FPC 6 are reinforced with metal frames 14. A fold-back portion 9 of the long-tail FPC 6 is folded back at 90 degrees so that flying lead 7 is disposed parallel with a turning shaft 21 of a carriage 20. The flying lead is then joined to a connection pad 26 on a main FPC board 24 using solder 18.
Claims20
A head support mechanism comprising:
- a flexure supporting a head slider;
- a load beam supporting said flexure and giving a load to said head slider;
- and
- a mount supporting said load beam;
- wherein a flying lead with plural flying lead members and a wiring pattern with plural wires connected to the flying lead members of the flying lead are provided at one end of the head support mechanism;
- wherein the plural flying lead members of the flying lead are spaced from each other by open spaces in a longitudinal direction of the head support mechanism;
- wherein the wiring pattern is covered with resin layer on both surface sides;
- and
- wherein one side of each of the resin layer is supported by a metal frame formed in the longitudinal direction of the head support mechanism, electrically insulated from said flying lead and said wiring pattern.
