Head support mechanism and magnetic disk device
View Patent ↗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.
