  • Patent number: 7336567
    Abstract: An optical head device including a lens holder which holds an objective lens, six wires for supporting the lens holder and a holder support member which movably supports the lens holder by the six wires in a tracking, focusing and tilt direction. The six wires comprise two pairs, each of the pairs comprising a composite wire composed of two wires and a single wire composed of one wire which are respectively disposed on an upper side and a lower side of the lens holder in the focusing direction. The spring constant of the composite wire is set to be approximately equal to a spring constant of the single wire. Alternatively, the six wires may be disposed on the same circumference with respect to a drive center in the tilt direction or the spring constant of one wire of the pair may be set to be smaller than spring constants of the other two wires of the pair.

  • Publication number: 20040264310
    Abstract: An optical head device has a holder support member supporting a lens holder. A combination of tracking and focusing drive coils, and drive magnets are used to move the lens holder in the tracking and focusing directions. A pair of corrective magnets are positioned on two sides of the lens holder in the tracking direction so as to form an open magnetic path. When the focusing drive coil is opposed to the drive magnets to displace the lens holder in the tracking direction, the focusing drive coil is also opposed to the pair of corrective magnets in order to prevent a tilting of the lens in the lens holder. Thus, the position of the lens holder can be maintained simply and inexpensively by using the pair of corrective magnets configured to provide an open magnetic path.
