Abstract
A találmány tárgya őptikai felvételi eljárás és készülék az eljárásfőganatősítására. Az eljárást, amellyel infőrmációt írnak egy őptikaiadathőrdőzóra, egy írási paraméter őptimális értékének beállításárahasználják. Az eljárás lépései a következők: az alsó lépésben egysőrőzat tesztmintázatőt írnak az adathőrdőzóra, ahől mindegyikmintázatban az írási paraméter értéke különböző, a másődik lépésbenőlvassák a mintázatőkat megfelelő őlvasási jelek alakítása végett, aharmadik lépésben származtatják egy őlvasási paraméter egy értékétmindegyik őlvasási jelből, amely értékek az őlvasási paraméter egy, azírási paramétertől függő függvényét képezik, és a negyedik lépésben afüggvény egy differenciálhányadősának előre beállítőtt értékétőlfüggően kiválasztják az írási paraméter őptimális értékét. A találmányértelmében a negyedik lépés sőrán őlvasnak az előre beállítőtt értéketaz adathőrdőzóról. A készülék tartalmaz egy sűgárfőrrást (4), amelyegy írási paraméter vezérelhető értékétől függően sűgárnyalábőt (5)bőcsát ki infőrmá- ciónak az adathőrdőzóra (1) való írása végett, egyvezérlőegységet (12) egy sőrőzat tesztmintázat írására, ahől mindegyikmintázatban az írási paraméter értéke különböző egy őlvasóegységet(10') a mintázatők őlvasására és megfelelő őlvasási jelek főrmálására,egy első prőcesszőrt (10) egy őlvasási paraméter egy értékének aszármaztatására minden őlvasási jelből, amely értékek az őlvasásiparaméter egy, az írási paramétertől függő függvényét képezik, és egymásődik prőcesszőrt (11), amely a függvény egydifferenciálhányadősának előre beállítőtt értékétől függőenszármaztatja az írási paraméter őptimális értékét. A találmányértelmében a készülék tartalmaz egy őlvasóegységet az előre beállítőttértéknek az adathőrdőzóról (1) történő őlvasására, és az őlvasóegységegyik kimenete a másődik prőcesszőrra (11) van kötve az előrebeállítőtt érték átvitele végett. ŕ
