Disc apparatus head slider support suspension

A wiring pattern (42, 43, 44, 45) having a small inductance and a small capacitance can be formed without increasing an equivalent mass of a suspension (30) supporting a head slider (80) in a disc apparatus. The suspension (30) elastically supports the head slider (80) having a head (82). A base portion (32) of the suspension is mounted to an arm (25) driven by an actuator (24). The head slider (80) is mounted on a head slider mounting portion (31 ) formed on an end of the suspension (30) opposite to the base portion (32). A tongue portion (35) is formed along a side of the base portion (32). The tongue portion (35) uprightly protrudes from the base portion (32). A head IC chip (90) is mounted on a head IC chip mounting portion (65) formed in the tongue portion (35).
