摘要： A data recording medium including a structure providing variable electromagnetic property (variable, resistance, capacitive, or other variable impedance or other variable electromagnetic property) contrast on the surface marking servo tracks. Such media include magnetic or optical storage disks and tapes. The media can be conductive metallic or nonmetallic and can be composed for example of poorly conductive media, dielectric media, or semiconductive media. The variable electromagnetic impedance can vary in the optical, electrical or other portions of the electromagnetic spectrum. A very small variation of the thickness of the protective layer above the magnetic recording medium is employed to mark the servo track information of the medium.
Information to be detected by means of a capacitive sensor can be recorded in the protective layer above or below the magnetic recording or optical storage medium. For example, a thin film metallic protective layer 0.07 micrometers thick can be patterned with about 0.02 micrometers of the protective layer. For a plated disk, the top 0.02 micrometers of the protective layer can be patterned.
A pattern for providing a variable impedance for representing data can be formed subtractively by sputter etching, or additively formed by a lift-off process or by deposition through a mask, or by the oxidation of or nitriding of materials such as Al, Si or valve metals.摘要翻译： 一种数据记录介质，包括在表面标记伺服轨道上提供可变电磁特性（可变，电阻，电容或其他可变阻抗或其他可变电磁特性）对比度的结构。 这种介质包括磁或光存储盘和磁带。 介质可以是导电金属或非金属的，并且可以由例如导电性差的介质，介电介质或半导体介质构成。 可变电磁阻抗可以在电磁光谱的光学，电学或其他部分中变化。 使用磁记录介质上方的保护层的厚度的非常小的变化来标记介质的伺服轨迹信息。 通过电容传感器检测的信息可以记录在磁记录或光存储介质上方或下方的保护层中。 例如，可以用约0.02微米的保护层对0.07微米厚的薄膜金属保护层进行构图。 对于电镀盘，保护层的顶部0.02微米可以被图案化。 用于提供用于表示数据的可变阻抗的图案可以通过溅射蚀刻减法或通过剥离工艺或通过掩模沉积或通过氧化或氮化诸如Al，Si或阀的材料 金属。

摘要： A carrier for microcircuit LSI chips (180) includes stacks (11) of parallel ceramic sheets (14) carrying thin conductive capacitor plates (20) laminated in a ceramic structure, in which the capacitor plates serve as power distribution conductors. Groups of plates provide electrical connection (19,21) beteeen power supply strips (16) and conductor straps (95, 98) which are connected to solder bonds (181) for the chips. This provides capacitance to smooth the power supply to high switching speed VSL1 chips. Stacks (11) of laminated ceramic capacitors serving as power planes are inserted into slots in laminated ceramic sheets. Signal vias (42) are provided about the periphery of the power planes. A highly parallel distribution of current is provided by means of horizontal power conducting straps which reduce voltage fluctuations, electrical resistance, and current per via.

摘要： A method and means is described for writing data on a recording medium, such as a disk or tape, containing servo samples in such manner that the number of servo samples is increased with a minimal increase in overhead (non-data) regions. The tracks on the medium are divided into a plurality of maxi sections, each of which contains all fields with servo and associated overhead information and also a data field. At least one micro servo section containing only a portion of said information is located within each data field. As each micro servo section passes by an associated recording head, writing and reading of data is temporarily interrupted, but resumed when the micro servo section moves beyond the head, in such manner as to require minimal resynchronisation of said data during reading. Using a phase continuous clock, data is written in both portions of a data field to either side of each micro servo section in one pass of the disk or tape relative to the head. The micro servo sections contain no timing reference address mark and require no data encoder/decoder flush or synchronisation byte to resume reading in the portion of the data field following each micro servo section.

摘要： 0 In a magnetic information storage device of the type having a slider which moves relative to a magnetic recording medium such as a disk, the slider has a non-rectangularly shaped air bearing surface that provides the slider with a high degree of stability. The non-rectangular shape is preferably either a triangle or a trapezium. The non-rectangularly shaped slider includes a tapered leading edge and a flat vertical surface as its trailing edge. A conventional thin film head element can be deposited on the vertical surface, if the slider is fabricated from ceramic material, or a conventional head element having a wound coil can be disposed on the vertical surface, if the slider is fabricated from ferrite material.
