Abstract
PURPOSE:To prevent the breakage and chipping of the tip parts of a recording and reproducing core and erasing core by providing the back bar of the erasing core to part of the recording and reproducing core and providing the back bar of the recording and reproducing core to part of the erasing core. CONSTITUTION:Part 1b of the recording and reproducing core 1 serves as the back bar of the erasing core 2 to constitute the magnetic circuit of the erasing core 2 and part 2b of the erasing core 2 serves as the back bar of the recording and reproducing core 1 to constitute the magnetic circuit of the recording and reproducing core 1. Part 1b of the recording and reproducing core 1 serves as a reinforcing material for the tip 2a of the erasing core 2 and part 2b of the erasing core 2 serves as the reinforcing material for the tip 1a of the recording and reproducing core 1. The breakage and chipping of the tip 10 of the recording and reproducing core 1 and the tip 2a of the erasing core 2 in the process for producing the magnetic head are thereby prevented and even the thin magnetic head core is produced without lowering the yield.
