Abstract

PURPOSE: To decrease an error rate of read data by interposing a selective reference- voltage generating method between a selective supply method for a sense current and polarity discriminator.
CONSTITUTION: Of magnetic bubble modules including at least one magnetic bubble sensing element (rdi) or (r'di), one side terminals are connected to polarity discriminator COMP via common signal amplifier SA, and other-side terminals are connected to switches S1 to Sn; between switches S1 to Sn, and polarity discriminator COMP, a selective reference voltage generating method, i.e. diode D' and resistance type potential divider T' are interposed. By adequately setting resistance (ri) of potential divider T', one polarity discriminator COMP can attain quantization by the best reference voltage with any module selected, so that the error rate of read data can be lowered.
