Abstract:
A flexure for mounting a plurality of reproduction elements thereon includes a metal base and an interconnection part. The metal base includes a first area, and a second area in which a window portion is formed. The interconnection part includes an insulating layer including a first lane which covers the first area and a second lane which covers the second area, a write trace pair connected to a recording element, read trace pairs provided on the second lane to face the window portion and connected to reproduction elements, respectively, and a ground trace arranged between two adjacent read trace pairs and provided with grounding points at two end portions.
Abstract:
An interleaved circuit has first branch conductors branching from a first conductor, second branch conductors branching from a second conductor, a metal base, an insulating layer of a dielectric, and a cover resin layer. The metal base comprises an opening. The first branch conductors and the second branch conductors are arranged alternately in a transverse direction of the insulating layer. A slit is formed in the insulating layer and the cover resin layer. The slit comprises a pair of opposite walls and an air gap between the opposite walls. Air introduced into the air gap forms an air layer. The slit extends longitudinally relative to the interleaved circuit along at least a part of the branch conductors.

The flexure includes a metal base, a conductive circuit along the metal base, and a tail pad in a flexure tail of the flexure. The tail pad includes first and second frames with an opening therebetween; a first pair of tail terminals arranged between and insulated from the first and second frames, connected to the first element; a second pair of tail terminals arranged between and insulated from the first and second frames, connected to the second element; and a third pair of tail terminals arranged between and insulated from the first and second frames, connected to a third element. First, second and third bridge elements of the metal base are arranged between first tail terminals, second tail terminals, and third tail terminals, respectively. A first bridge-free opening portion is between the first and second tail terminals, and a second bridge-free opening portion is between the first and third tail terminals.
Abstract:
A flexure tail is provided in a flexure including a metal base and a conductive circuit portion. The flexure tail includes a tail pad portion. In the tail pad portion, tail electrodes to are arranged. At the tail pad portion, a stub which remains after a test pad portion is cut off is formed. The stub includes conductors to which are left uncut. The conductors to which are left uncut are electrically connected to the tail electrodes to, respectively. The stub includes a bent portion. The bent portion is formed by bending a frame portion of the tail pad portion, and forms an angle of 30° or more with respect to a circuit board. The tail electrodes to are joined to terminals to of the circuit board.
