摘要： A flying head mechanism includes a flying head, a suspension and an actuator which applies a load force through the suspension. The load force applied by the actuator is adjustable while the head is in operation. The actuator may actively control load force as part of a feedback loop which maintains the flying head at a constant flying height. One embodiment disclosed includes a voice coil actuator. In embodiments using an optical flying head, a conventional focus sensor may provide a signal indicative of flying height, since the focus signal inherently indicates flying height error. The flying head includes a contact sensor which detects head/disk contact. The head further includes means for changing the focus of the optical elements, without changing the flying height of the head. The entire suspension is mounted in a shock and vibration immune configuration. Two heads may be used in some embodiments, in which more than one type of media may be read or written by the disk drive.
摘要翻译：飞头机构包括飞头，悬架以及通过悬架施加载荷力的致动器。执行器施加的载荷力可以在头部运行时调节。致动器可以主动地将负载力控制为反馈回路的一部分，其将飞行头保持在恒定的飞行高度。所公开的一个实施例包括音圈致动器。在使用光学飞行头的实施例中，传统的聚焦传感器可以提供指示飞行高度的信号，因为聚焦信号固有地表示飞行高度误差。飞头包括检测头/盘接触的接触传感器。头部还包括用于改变光学元件的焦点的装置，而不改变头部的飞行高度。整个悬架安装在一个震动和振动的免疫结构。在一些实施例中可以使用两个头，其中可以由盘驱动器读取或写入多于一种类型的介质。

摘要： An phase change optical medium compatible with a flying head can include a substrate, a reflective layer, a first dielectric layer, a phase change information carrying layer, a second dielectric layer and a lubricant layer. The structure and materials used both protect the phase change layer from mechanical damage due to impact and from information-altering heat generated by impact.

摘要： An air bearing assembly for an optical drive carries a solid immersion lens (SIL) having a bottom surface facing the disk contoured such that a central region where the optical path exits the bottom surface is closest to the recording medium regardless of perturbations in the attitude of the air bearing and neighboring points on the surface surrounding the central region recede for clearance but function at least partly as an air bearing. In one embodiment the bottom surface of the SIL has a radius of about 10 meters.

摘要： A light detection apparatus includes at least one re-imaging lens that re-images a light beam reflected from an optical storage medium, to form an image of a light spot formed by the light beam on the storage medium. At least one detector detects a selected portion of the image The selected portion of the image contains only such information as is encoded on a region of the optical data storage medium that is illuminated by a corresponding portion of the light spot.

摘要： An apparatus for storing and reading a magneto-optical disk has a slit shaped aperture located in an air-bearing slider which flies above the disk. Domains of the disk are selected for storing or reading by a light beam. The domains are reduced in size without losing inter-domain resolution by illuminating the disk with the portion of a focused laser beam incident on the disk through the slit, the slit width being less than the full beam width. The slider preferably terminates a wedge-shaped cavity suspended above the medium a distance substantially less than the wavelength of the illuminating light; the thickness of the edges of the slit being substantially less than the wavelength of the illuminating light.

摘要： A rotary actuator for an optical head comprises a pair of reflectors mounted respectively on the end of the arm and on the pivot axis to define an optical path via the arm to an optical disk for an external beam directed along the pivot axis. Special arm geometry reduces variable head skew and consequent image rotation. A multiple platter design features optical switches effectively aligned on the pivot axis.
