摘要： PURPOSE:To mass-produce inexpensively stable products while avoiding troublesome bend forming by using completely separate focusing plate and tracking plate springs as a couple and connecting both of them via a relay member. CONSTITUTION:A support mechanism is constituted by a couple of focusing plate springs 4a, 4b, the relay member 5 and a couple of tracking plate springs 6a, 6b. A couple of focusing plate springs 4a, 4b and a couple of tracking plate springs 6a, 6b are constituted by having only to cut plate springs at a proper length, and since no bending forming required for a conventional head is necessary, the manufacture is easy. A couple of focusing coils 9a, 9b are fixed to a side face opposing to the tracking direction T of the support member 2 and a couple of tracking coils 10a, 10b are mounted incorporatedly to the outside of the focusing coils.

摘要： PURPOSE:To drive stably an objective lens by a small-sized and light constitution by connecting focusing use and tracking use plate springs through a repeating member, and providing a coil for generating a magnetic field on the surface orthogonal to the optical axis. CONSTITUTION:Each one end of a pair of tracking T use plate springs 8a, 8b and focusing F use plate springs 6a, 6b opposed in parallel is connected to a repeating member 7, and the springs 8a, 8b are opposed at an angle alpha, therefore, the springs 6a, 6b are not twisted even by a movement of the T direction, and an objective lens 1 can be supported so that it can move in the F direction and the T direction. The springs 6a, 6b, 8a and 8b are shaped like a plate and can be manufactured at a low cost. Since coils 12a, 12b and 13 for driving the objective lens 1 is installed to a lens supporting member 2, a size of the optical axis direction becomes small and a device can be made small-size and light in weight, the objective lens can be bright to a driving control stably and with a high accuracy by concentrating the center of gravity of the movable part, and the assembly can also be executed easily.

T use coils 35a, 35b are brought to an electric conduction, and by a magnetic field of magnets 36a, 36b, the lens 21 supported by the T use springs 26a, 26b is displaced in the T direction. In this case, a pair of T use springs 26a, 26b are opposed to each other at an angle alpha, therefore, the F use springs 24a, 24b are not deformed, and the lens 21 is driven exactly. Accordingly, the objective lens can be brought to a driving control stably in the focusing direction and the tracking direction.
