Suspension and disk unit

A suspension comprising:

• a load beam that connects a head to a head arm, the head recording data onto and reproducing data from a disc, the head arm moving the head to a target position on the disc, said load beam compressing the head against the disc with a certain compression force;
• a flexure that supports the head;
• a dimple as a projection that enables said load beam to point-contact said flexure, and the head to pitch and roll around the dimple;
• and
• a preamp chip, connected to said load beam, which amplifies a signal to be sent to the head,
• wherein said load beam includes:
• a spring section that applies the compression force;
• a rigid section that extends from the spring section to a side opposite to the head arm, and is more rigid than the spring section in a direction, in which a distance between the head arm and the disc fluctuates;
• and
• a balancer section connected to the dimple and preamp chip, and more elastic than the rigid section in the direction, the balancer section extending from the rigid section to a side of the rigid section opposite to the spring section.

• and
• a preamp chip, connected to said load beam, which amplifies a signal to be sent to the head,
• wherein said preamp chip is located symmetrical to the head with respect to said load beam.

A disc unit comprising:

• a head that records data onto and reproduces data from a disc;
• a head arm that moves said head to a target position on the disc;
• and
• a suspension, connected to said head arm, which supports said head;
• said suspension includes:
• a load beam that connects a head to a head arm, the head recording data onto and reproducing data from a disc, the head arm moving the head to a target position on the disc, said load beam compressing the head against the disc with a certain compression force;

• wherein said preamp chip is located symmetrical to the head with respect to said load beam.
