1. A data recording and retrieval system, comprising:
- an enclosure housing therein a motor and a magnetic disk connected with and driven by said motor for rotation within said enclosure;
an actuator, pivotally mounted within said enclosure;
a suspension, connected with said actuator;
a magnetic device embodied within a slider and capable of generating and receiving electrical signals, connected with an end of said suspension, said suspension holding said slider proximal to a surface of said disk;
first circuitry conducting said electrical signals from said slider to a junction;
second circuitry electrically coupled with said first circuitry at said junction;
said junction including a shaped female connector portion integral with one of said first and second circuitry and having a socket formed therein, and a male connector portion integral with the other of said first and second circuitry said male portion configured for coupling with said socket of said female portion, said male and female connector portions being constructed by a patterning process, wherein said male and female connector portions mate in a force fit connection.

Abstract
A system and method for connecting flexible circuitry in a disk drive system such as that used in computer systems. The system and method allow a large number of traces to be connected in a small area by forming male and female connector portions at an end of a mating pair of traces. the male and female portions are formed using conventional flexible circuit fabrication techniques, making possible very accurate control of very small built-in type connectors. The connection can be uncoupled and re-coupled, and added security of attachment can be achieved through the use of ultra-sonic bonding and use of a mechanical clamp.
