摘要： The present invention relates to a method and apparatus for dynamically positioning the objective lens in an optical disk drive to maintain focus despite loss of perpendicularity between the light beam and the information layer of the optical disk. Loss of perpendicularity may occur as a result of any number of factors, including irregularities in the manufacture of the disk, manufacturing tolerances and assembly of the disk drive components, bearing defect frequencies, shock and vibration. Failure to maintain perpendicularity may interference with the ability of the optical pick up unit of the drive to accurately read and write. The tilt focus mechanism of the present invention utilizes a rotary actuator that positions the objective lens in three dimensions relative to the surface of the optical disk. In one embodiment, a first voice coil motor positions the actuator generally in two dimensions parallel to the surface of the disk and a second voice coil motor positions the objective lens generally along an arcuate path orthogonal to the surface of the disk.

摘要： The present invention relates to a laminated actuator assembly and the method for making the actuator assembly. The actuator assembly is intended for use in miniature personal electronic devices, but could be used in any type of disk drive. The actuator is primarily constructed from strong, stiff, lightweight composite materials. The upper and lower planar elements of the actuator assembly, each comprising multiple composite layers, include a forward portion and a rearward portion. A flexure member, typically positioned between the layers of composite material, allows the forward portion of each planar element to pivot in unison relative to the rear portion of each planar element. In this manner, the position of an optical pick up unit or other read/write device positioned at the distal end of the actuator assembly can be adjusted relative to the surface of a data disk. The composite and flexure planar elements are formed in arrays of multiple component pieces with aligned registration members. The registration members provide accurate alignment during assembly. Adhesive is applied in appropriate quantities to fully fill the space between the upper and lower layers, without seepage at the edges. By assembling the actuator components in arrays, the miniature actuator assemblies can be easily handled and the electronic, optic and magnetic subassemblies can be attached more easily.
摘要翻译：本发明涉及层压致动器组件及其制造方法。致动器组件旨在用于微型个人电子设备中，但可用于任何类型的磁盘驱动器。致动器主要由坚固，刚性，轻质的复合材料构成。每个包括多个复合层的致动器组件的上和下平面元件包括前部和后部。通常位于复合材料层之间的弯曲构件允许每个平面元件的前部相对于每个平面元件的后部一致地枢转。以这种方式，可以相对于数据盘的表面调整位于致动器组件的远端处的光学拾取单元或其它读/写装置的位置。复合和弯曲平面元件形成为具有对准的配准构件的多个部件的阵列。配准部件在组装过程中提供准确的对准。施加适当的粘合剂以完全填充上层和下层之间的空间，而不会在边缘处渗漏。通过将致动器部件组装在阵列中，可以容易地处理微型致动器组件，并且可以更容易地连接电子，光学和磁性组件。

摘要： Various configurations of cartridges for optical disks, particularly first-surface optical disks, are provided. The cartridges include a plurality of protectors for use in safeguarding the optical disk when certain conditions are present or certain events occur. The protectors include an elongated shutter that covers the hub assembly, at least annular slot portions inside of the cartridge to restrain movement of the disk within the cartridge, a locking subassembly to hold the shutter in a desired position, and a mechanism for preventing complete insertion of the cartridge into an optical drive when the cartridge is in the wrong orientation relative to the drive.
