摘要： An optical head driving mechanism is applied to an optical disc driver that has a base plate, a pair of guide rods and an optical module movably mounted on the guide rods. The driving mechanism includes a base, a movable member, a piezo-actuator and at least a resilient member. The piezo-actuator and the movable member generate proceeding waves at the rim of the piezo-actuator and move the optical module along the guide rods when the piezo-actuator activates.

摘要： A film layer separation device for multilayer disks is disclosed. With the help of a stamper made of magnetic materials, the film layer separation is achieved through the attractive force imposed on the stamper by electromagnetic tearing. The device contains at least: a stamper supporter for supporting the stamper, an electromagnetic attraction device, and a base fixture. To distribute the electromagnetic force on the stamper evenly, the electromagnetic attraction device can have an array of homogeneously disposed electromagnetic iron cores and a conductive coil that can generate a magnetic force. Thus, there will be no localized stress when tearing.

摘要： An electromagnetic transmission device. A guide bar connects to a fixed base and includes magnetic-permeable material and a first central height plane. A coil connects to the fixed base. A support base movably fits on the guide bar. An annular magnetic member connects to the support base and is surrounded by the coil. A magnetization direction of the annular magnetic member is perpendicular to a moving direction of the support base and annular magnetic member. The annular magnetic member includes a second central height plane. The coil interacts with the annular magnetic member to generate a first force. When moving to separate the second central height plane from the first central height plane, the annular magnetic member interacts with the guide bar to generate a second force, driving the support base and annular magnetic member to move along a direction perpendicular to the magnetization direction of the annular magnetic member.

摘要： A spindle motor inclination angle adjusting mechanism for an optical disk device includes two adjusting mechanisms to provide two rotational freedom for the base dock of the spindle motor to adjust the inclination angle of the spindle motor. The first adjusting mechanism has three support points that are not on the same straight line to support the base dock. Two of the support points are fixed and the third support point is movable relative to the other two support points to change the inclination angle of the base dock of the spindle motor. The second adjusting mechanism is a rotary element for carrying the first adjusting mechanism and driving the first adjusting mechanism to rotate and change the direction of the inclination angle of the base dock to adjust the spindle motor inclination angle.

摘要： A magnetic bearing includes a base, a spindle rotatably mounted onto the base and a magnetic portion mounted between the base and the spindle to provide a magnetic repulsion that suspends the spindle. The magnetic portion further includes an inner magnetic portion and an outer magnetic portion that repulse against each other. The outer magnetic portion is located around the inner magnetic portion so that the inner magnetic portion and the spindle are suspended. Therefore, mechanical friction in the magnetic bearing is minimized.
