PURPOSE:To improve the reproducing sensitivity, by adhering an auxiliary magnetic plate to an axiliary magnetic pole. CONSTITUTION:A magnetic recording/reproducing heat contains a main magnetic pole 6, an auxiliary magnetic pole 7 of a ferrite thin plate, a rectangular parallelepiped auxiliary magnetic plate 8 and a coil 9. The graphs A and B show the reproduced outputs with a plate 8 and with no plate 8 respectively. Thus the reproduced output is improved by about 2-5 times with addition of the plate 8. |
