Abstract

PURPOSE: To enable to read out consecutive information with good efficiency, by providing two detection elements alternately meandered in one pitch of the magnetic substance pattern on the transfer path.
CONSTITUTION: Two detection elements 21, 22 forming a detector are arranged alternately in meandering state in one pattern pitch on the same transfer path. By the differential amplification of the output of the both detection elements, the noise component due to rotating drive magnetic field is cancelled and only the signal component by magnetic bubble can be detected. Accordingly, the consecutive magnetic bubble information can be read out with good efficiency. Since two peaks with different polarities can be generated in one rotating magnetic field period, greater detected output can be obtained by reading out the difference of the both peaks.
