Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 既存の設備を用いて、磁気バーの立上り端部 で発生した信号を増幅器で増幅した信号と磁気バーの立 下り端部で発生した信号を増幅器で増幅した信号とが略 等しい振幅を有するようにした磁気パターンを提供す る。 【構成】 パターン状に並設された磁気バー(1)から なる磁気パターンであって、カード読取り用の磁気ヘッ ドが各々の磁気バー(1)の立上り端部(2)と立下り 端部(3)を所定速度で走査する時に発生する信号 (4、5)を所定の応答速度の増幅器で増幅して情報を 得る。磁気パターンは、立上り端部(2)で発生した信 号(4)を増幅器で増幅した信号(6)と立下り端部 (3)で発生した信号(5)を増幅器で増幅した信号 (7)とが略等しい振幅を有するように、前記立上り端 部(2)で発生した信号または立下り端部(3)で発生 した信号を補正することを特徴とする。 (57) [Abstract] [Purpose] Using the existing equipment, the signal generated at the rising edge of the magnetic bar is amplified by the amplifier and the signal generated at the falling edge of the magnetic bar is amplified by the amplifier. Providing a magnetic pattern in which and have substantially equal amplitudes. A magnetic pattern comprising magnetic bars (1) arranged side by side in a pattern, wherein a magnetic head for card reading has a rising end (2) and a falling end (of a magnetic bar (1). Signals (4, 5) generated when scanning 3) at a predetermined speed are amplified by an amplifier having a predetermined response speed to obtain information. The magnetic pattern has a signal (6) obtained by amplifying the signal (4) generated at the rising edge (2) with an amplifier and a signal (7) obtained by amplifying the signal (5) generated at the falling edge (3) with an amplifier. The signal generated at the rising edge (2) or the signal generated at the falling edge (3) is corrected so that and have substantially the same amplitude.
