摘要： A read-write head positioning device and method of operation that provide coarse and fine positioning using only one actuator. The read-write head is mounted on a carriage (502). The carriage is resiliently mounted to a moving frame (504). The moving frame is slidably mounted to a fixed frame (516). A detent mechanism (518, 520) disposed between the fixed frame and moving frame provides coarse positioning of the moving frame in several discrete positions relative to the fixed frame. An actuator (528) disposed between the fixed frame and carriage provides for fine positioning of the transducer. To change coarse positions, the actuator drives the carriage in the desired direction to engage a mechanical stop (508, 510) on the carriage with a stop abutment (512, 514) on the moving frame. The actuator then continues to drive the carriage and the moving frame in the desired direction causing the detent mechanism to release from its current coarse position. When the detent mechanism captures the moving frame in the desired coarse position, the actuator backs the mechanical stop away from the stop abutment and resumes fine positioning operations.
摘要翻译：一种读写头定位装置和操作方法，仅使用一个致动器来提供粗略和精确的定位。读写头安装在托架（502）上。托架弹性地安装到移动框架（504）上。移动框架可滑动地安装到固定框架（516）上。设置在固定框架和移动框架之间的制动机构（518,520）提供移动框架相对于固定框架在几个离散位置的粗略定位。设置在固定框架和托架之间的致动器（528）提供换能器的精细定位。为了改变粗略位置，致动器以期望的方向驱动托架，以使滑架上的机械止动件（508,510）与移动框架上的止动支座（512,514）接合。然后，致动器继续沿所需方向驱动滑架和移动框架，使得止动机构从其当前的粗略位置释放。当止动机构将移动框架捕获在所需的粗略位置时，致动器将机械止动件远离止动支座并恢复精确的定位操作。

摘要： An improved servo system having an optical head array integrated into the magnetic head, and optical servo tracks incorporated on the magnetic side of a medium. The optical head array includes a light source array that individually illuminates the optical servo tracks through a beam splitter array and a lens array. Light beams incident on the optical servo tracks are individually reflected back through the lens array and beam splitter array to respective bi-cell photo detectors. The signals from the bi-cell photo detector are amplified by respective differential amplifiers to produce error signals indicative of the alignment of the magnetic head with the optical servo tracks. The error signals are combined by a circuit to produce a position error signal.

摘要： Disclosed is an optical sensor used for remote laser level monitoring in liquid storage vessels. The sensor is mounted directly to a standard tank nipple, located on top of the vessel, by a threaded connecting means and is linked to a laser measurement device via fiber optic cabling. The level in the vessel is measured as a function of the time required for a laser signal to be transmitted from the sensor, reflected off the liquid surface and returned to the receiver lens located in the sensor.

摘要： Method of manufacturing a thin-film magnetic head comprising an inductive transducing system. A non-magnetic, insulating material for forming a first insulation layer (13), on which an inductive transducing element (15) is formed, is deposited on a plane basic surface (11). Subsequently, a non-magnetic, insulating material for forming a second insulation layer (19) is deposited on the first insulation layer and the inductive transducing element formed thereon. Subsequently, material is removed in an area proximate to a head face (30) to be formed for forming an aperture extending through the first and the second insulation layer and reaching as far as the basic surface, whereafter a non-magnetic, insulating material for forming a gap layer (29) is deposited in the aperture. Subsequently, a soft-magnetic material for forming a first soft-magnetic layer is deposited on the gap layer, whereafter the soft-magnetic layer (31), as well as adjoining, uncovered layer parts of deposited non-magnetic, insulating material are planarized to form a plane surface. Subsequently, a soft-magnetic material is deposited on this surface for forming a second soft-magnetic layer (35) which, jointly with the first soft-magnetic layer, constitutes a magnetic flux guide (36).

摘要： A voice coil driven positioner is provided for positioning the magnetic head of a tape drive relative to the tape of a removable tape cartridge. The head positioner includes a low-mass carriage that supports the head on one end and the voice coil on an opposed second end. A low friction guide mechanism guides the carriage along a precision movement path that carries the head across tracks of a supplied multi-track tape and simultaneously carries the voice coil through a flux field generated by a stator. A movable portion of a position detector is attached to the carriage and located within the hollow of the voice coil for reciprocating into a hollow passageway of the stator together with reciprocation of the voice coil into another hollow of the stator. A fixed portion of the position detector is attached to the stator and located compactly within the hollow passageway of the stator. A programmable lookup table converts measurement signals output by the position detector into pre-calibrated, head-position indicating signals. A platform is provided on the carriage for mounting an interferometer prism used during calibration.
