Magnetic spring arm assembly including structure for preventing damage to a conductive layer resulting from bending |
摘要 |
A magnetic head unit is provided by which damage to a conductive-pattern layer formed on a spring arm during a bending process of the spring arm can be prevented. The magnetic head unit comprises a magnetic head and a spring arm having a bent portion which is bent to generate an elastic force. The magnetic head is mounted on an end of the spring arm. At least one conductive-pattern layer is formed on a surface of the spring arm to extend from a gimbal portion where the magnetic head is mounted to a attachment portion where the spring arm is mounted to a member of a magnetic head driving mechanism. The bent portion has a first portion and a second portion separated from the first portion. The conductive-pattern layer passes through the second portion. No external force is applied to the conductive-pattern layer formed during a bending process for the bent portion. A dispersing-pattern layer may be provided for dispersing an external force exerted on the conductive-pattern layer during the bending process of the bent portion so that said conductive-pattern layer is protected from being damaged due to the external force being concentrated onto said conductive-pattern layer.
