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.

摘要： PURPOSE:To set greatly a driving control range of an objective lens, and to improve the performance by a small-sized device by providing a means for driving the lens in the focusing direction, between a supporting point of a mechanism for supporting the objective lens so as to be freely movable, and the objective lens. CONSTITUTION:An objective lens 1 is supported in the F direction and the T direction by focusing F use springs 6, 7 and tracking T use springs 9, 10, which are connected through a repeating member 8. F use and T use coils 15-17 are installed to a substrate 3, and the lens 1 is driven by a magnetic field of a yoke 18 and a magnet 19. The F use coil 15 is placed in a free space of between the lens 1 and the repeating member 8, therefore, even if its deviation quantity is small, a driving control range of the lens can be set greatly by deviating greatly the lens 1 by using the repeating member 8 as a supporting point. Since the coils 15-17 are flattened and arranged effectively in the free space, the device can be made small in size, and the performance of the optical head can be improved.

By a shape variation of this spot, a focused state is detected, and since the concave and the convex lenses 15, 16 have been used, the astigmatism becomes large, the detecting sensitivity is improved and the dynamic range is widened, and the positions of the focal planes F
1 , F
2 can be set independently and optionally, therefore, the degree of freedom for arranging the photodetector can be enlarged.
