MAGNETIC READ/WRITE HAVING A REDUCED THICKNESS CLOSURE CORE |
摘要 |
This invention relates to a wide-write/narrow-read head having a pair of C-shaped cores one of which is used as a read core and the other of which is used as a write core, and a closure core which is provided between the two cores to shut off side magnetic circuits at the time of data reading. The closure core is reduced in thickness at the tip end and is shaped to slope toward the rear head so as to increase magnetic resistances from said closure core to said read core in order to prevent the magnetic flux extending between said write core and said closure core from leaking into said read core from said closure core.
