Abstract
PURPOSE: To make it possible to read address information correctly by recording the address information by using not less than two kinds of patterns after the address information is differently converted, when the address information is recorded on each tracks not less than twice.
CONSTITUTION: When address information is recorded not less than twice, e.g., twice, latter address information 11 is recorded in a pattern differing in magnetic recording characteristics from former address information 10 and being given the same meaning. Namely, when the former is denoted as A(1011), the latter is passed through an inverting circuit to record A'(0100). Thus recorded address information is read out by the circuit consisting of inverter N inverting either read address information, AND gate A1 for AND between the output of this inverter N and the other, and exclusive-OR gate EOR for OR between the output of inverter N and the other.
