摘要： A magnetic recording method using a magnetic head to record information in an information recording medium and read the information recorded on the information recording medium is such that the temperature of a portion of the information recording medium on or from which information is recorded or read is changed in order to record or read information. A disk device having the ability to record and read information comprises a magnetic head for recording information by applying a given magnetic field to an information recording medium and reading the information from the information recording medium; and a temperature changing mechanism for changing the temperature of a portion of the information recording medium on or from which information is recorded or read. The magnetic head is moved to the portion of the medium in which a temperature change is produced by the temperature changing mechanism, whereby information is recorded or read.

摘要： A magnetic head for perpendicular magnetic recording system which assures low write current and high recording reproduction efficiency by using a flat coil and increasing the number of turns of the coil. The flat coil is formed on a substrate and a main pole piece is arranged in the center of the coil and vertically to the surface on which the coil is formed. This magnetic head is suitable particularly for manufacture as a thin film magnetic head.
摘要翻译：用于垂直磁记录系统的磁头，通过使用扁平线圈并增加线圈的匝数，确保低写入电流和高记录再现效率。扁平线圈形成在基板上，主极片布置在线圈的中心并垂直于形成线圈的表面。该磁头特别适用于制造薄膜磁头。
