Abstract

PURPOSE: To ensure a normal function of writing at the point in time of detection of deterioration in read function by forming a magnetic head with a recording and reproducing heads made in one while the gap depth of the magnetic head is made greater than that of the reproducing head.
CONSTITUTION: Recording head 1 with gap 7 formed by butting core 4 wound with coil 6 against core 5 with interposing spacer 8, and reproducing head 2 with gap 12 formed by butting core 9 wound similarly with coil 11 against core 10 with interposing spacer 13 are joined in one with shield plate 3 between the both to form a two-gap head, where depth (a) of recording gap 7 of recording head 1 is made greater than depth (b) of reproducing gap 12 of reproducing head 2. In case of long- term use, the gap of reproducing head 2 wears earlier between two above mention head cores, which causes a read defect, and on detection of it, the head is replaced to prevent a write-defective card from being issued.
