摘要:
A thin film magnetic head for use with a magnetic recording medium having a direction of movement, includes a substrate and a plurality of magnetic read/write cores disposed on the substrate. At least a part of each core is formed of a magnetic thin film deposited on the substrate. Each of the cores includes a magnetic gap disposed between the magnetic read/write core and the substrate, the magnetic gaps being aligned with each other in the same position relative to the direction of movement of the magnetic recording medium. Each magnetic gap is separated an identical distance from the substrate, and each of the cores has a different width for forming a different width track on the magnetic recording medium.

A magnetic recording medium is formed by disposing on a substrate a magnetic recording layer comprising a vertically magnetizable film of Co alone or a Co alloy, or Fe alone or a ferromagnetic Fe alloy. The lubricity, wear resistance and corrosion resistance of the magnetic recording medium are improved by forming an upper layer of Co oxide on the magnetic recording layer. The upper layer per se can be a magnetizable film, particularly a vertically magnetizable film.

There is provided a method of producing an organic EL light-emitting device which enables prevention of crosstalk between adjacent pixels of the same color. Provided is a method of producing an organic EL light-emitting device which has banks provided in a row direction and in a column direction, and a plurality of organic EL light-emitting portions isolated from each other by the banks. The method includes the steps of forming banks such that a height of a bank portion of a row direction and a height of a bank portion of a column direction are different from each other; and applying an organic EL material in a continuous manner along the bank portion which is higher of the bank portion of the row direction and the bank portion of the column direction, between the banks of the higher bank portion.

The present invention provides a domain wall displacement-type magnetooptical recording medium effective for decreasing jitter, in which a conventional herringbone recording mark can be changed to a linear mark. The magnetooptical recording medium of the present invention includes a substrate having lands and grooves, and a magnetic layer deposited on the substrate so as to be magnetically interrupted between the lands and the grooves, wherein the magnetic film deposited on each of the lands has a section having a flat bottom, and a substantially flat top in the central portion of each of the lands, either side having a thickness decreasing in the direction to the side end.
