INFORMATION RECORDING MEDIUM, PAINTING METHOD OF ELECTRICALLY CONDUCTIVE PAINT, MANUFACTURE OF MAGNETIC RECORDING MEDIUM, HEAD UNIT, ROTARY HEAD, TRACKING SERVO CONTROLLER AND INFORMATION RECORDING-REPRODUCING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide the information recording medium, in which the density in the track width direction of a magnetic recording medium is made higher and the recording density is also made higher and a tracking servo control is conducted, the head, which is applicable to the information recording medium, and the information recording.reproducing device. ;SOLUTION: A substrate 12, which is electrically conductive, is provided on a supporting body 10. Surface shapes 12A (12B), which are formed on the surface of the substrate 12, provide tracking information. Then, a magnetic layer 14 is formed as an upper layer on the shapes 12A (12B) to complete the medium. Employing the above constitution, the magnetic head, which conducts an information recording.reproducing, and the pickup portion, which detects an electrostatic capacitance, are integrally slided. Thus, an information recording and reproducing is performed by the head and a tracking servo control is conducted employing the electrostatic signals.;COPYRIGHT: (C)1999,JPO
