Title: Magnetic head positioning system
Inventor: HATSUTORI TOSHIAKI
IPC: G11B21/10
Filed: 1983-10-31
Abstract: PURPOSE:To increase the position detection sensitivity of a head and to improve the positioning accuracy by increasing a position error pulse in response to the moving disance from the center of head without increasing especially the bit number of an up-down counter of a microcomputer. CONSTITUTION:In an envelope 90, (PU-beta)-(PD-beta) is taken as error information to a position shift of a head. When no position shift of head exists, this value is zero. When the head is shifted left from the center, the error information is (PU-beta)-(PD-beta)<0. A pulse signal is generated from a servo demodulator 14 based on this numerical value. This value is compared by the microcomputer and when the up-value and the down-value are equal, the head is positioned to the center. A command is outputted to a controller 12 to drive a positioning mechanism 10. Since the pulse number corresponding to the position error information is larger than conventional numbers, the positioning with high accuracy is attained.
