VOIDLESS CERAMIC METAL HALIDE LAMPS

A voidless CMH lamp and a method of making such a lamp are provided. The CMH lamp includes a lamp body that receives at least one end plug. The end plug is constructed from a core of cermet material received within an outer layer of a ceramic material. An electrode is placed into the cermet material.

Disk file or tape drive with high servo sample rate

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 resynchronization 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 synchronization byte to resume reading in the portion of the data field following each micro servo section.

Laminated magnetic structures with ultra-thin transition metal spacer layers

Non-magnetic transition metal spacer layers 2.5 to 50 Angstroms thick with compositions of Os, Ru and Re are used in laminated magnetic structures. The ultra-thin non-magnetic transition metal spacer layers are useful to fabricate micron and sub-micron laminated magnetic devices. The laminated magnetic structures using ultra-thin non-magnetic transition metal spacer layers of Os, Ru and Re have anti-ferromagnetic coupling between the magnetic layers. The anti-ferromagnetic coupling provides a mechanism for reduced edge curling and efficient directional magnetization. Alloying the non-magnetic transition metal layer provides a method for engineering coupling strengths, coercivities and remanences in magnetic structures useful for high frequency applications. These laminated magnetic structure have applications in magnetic read head, magnetic write head, magnetic memory, and miniature transformer devices.
