ABSTRACT:
An actuator for moving a recording head in a radial direction of a recording disc includes a first member and a second member. The first member has a first actuator body and a driving coil adhered to said first actuator body by a adhesive, and the second member has a second actuator body and a bearing mechanism which is provided to said second actuator body. The recording head is mounted on at least either said first actuator body or the second actuator body, and said first member and the second member pivot on said shaft which is fixed on a base and is engaged with said bearing mechanism of said second member due to an operation of said driving device of said first member so that the recording head is moved in the radial direction of said recording disc. In the production of the actuator, the first member and the second member separately produced and then the first member and second member integrated with each other.
