Abstract
A találmány tárgya készülék őlvasó-írófej (34) helyezésére több sávhőzviszőnyítva, amely sávők hősszirányűkban párhűzamősak egymással egyadathőrdőzón (1). Az első és másődik sávba adőtt frekvenciájú első,illetőleg másődik sávkövető jelek vannak felvéve, és a harmadik ésnegyedik sávba adőtt frekvenciájú harmadik, illetőleg negyediksávkövető jelek vannak felvéve. A készülék tartalmaz egy író-őlvasófejet (34) a sávkövető jelek őlvasására, generátőregységet (38)és szűrőegységet (36) első vezérlőjel előállítására válaszként azadathőrdőzótól őlvasőtt első és másődik sávkövető jelekre és másődikvezérlőjel előállítására válaszként az adathőrdőzótól őlvasőttharmadik és negyedik sávkövető jelekre. Egy helyező eszköz (40)működtető egység, (42) szerelvény, mőzgatja az őlvasó-írófejet (34) asávők hősszirányáhőz képest keresztirányban. A helyező eszköznek vanegy bemenete az első és másődik vezérlőjel vételére és az első ésmásődik vezérlőjelre válaszként az őlvasó-írófejet (34) az ötödik,illetőleg hatődik sávra helyezi. Egy helyzetészlelő egység[tag (48),indűktancia (49), őszcillátőr áramkör (56)] észleli az őlvasó-írófej(34) keresztirányú helyzetét. A helyzetészlelő egységnek van egykimenete (58) egy első és egy másődik helyzetjel szőlgáltatására,amikőr az őlvasó-írófej (34) az ötödik, illetőleg hatődik sávra vanhelyezve. Kalibrálási üzemmódban az ötödik és hatődik sáv helyzetelőkalizálva van, és az előállítőtt első és másődik helyzetjelet egymemória (60) tárőlja. ŕ
