Magnetic head assembly for a flexible disk drive having grooves formed in the core of the erase head which most closely adjoins the pair of cores forming the write/read head

摘要

In a magnetic head assembly for a flexible disk drive, a write/read head and an erase head are formed with grooves defining track widths only in I-shaped cores thereof. Erase track widths are dimensioned 53 &mgr;m to 63 &mgr;m each while a track width is dimensioned 125 &mgr;m to 135 &mgr;m. These dimensions correct the extension of magnetic fluxes from gaps. Hence, the assembly does not lower the reproduction output or erase the data of adjoining tracks, thereby insuring compatibility of magnetic recording media or disks.
