摘要： A tunnel erasing-type magnetic head having a short distance between the gaps, wherein a second core half is sandwiched between the first core half and the third core half, a magnetic gap for recording and reproducing the signals is formed between the first core half and the second core half, and a magnetic gap for erasing is formed between the second core half and the third core half, so that the second core half can be utilized for both recording and reproducing the signals and erasing the signals. The second core half is obtained by forming a thin magnetic film of a high saturation flux density on the base portion composed of a nonmagnetic material that forms the magnetic gap. The first and third core halves are also obtained by forming a thin magnetic film of a high saturation flux density on the magnetic gap surfaces of the base portions to produce performance that can be used for the magnetic recording media having high coercive force. The magnetic head has a short distance between the gaps. When used for a floppy disk apparatus, therefore, there does not develop under-erasing or over-erasing even for small disks, and the effective track width does not decrease, either. This head can be used also as the one in which an ordinary erasing head element and a recording and reproducing head element are combined together.

A magnetic head is mounted on the rotating drum, and a magnetic recording medium is wound on the rotating drum, and the rotating drum is rotated so as to read and write signals. Alternatively, the magnetic recording medium is mounted on the rotating drum, and signals are read and written by a magnetic head fixed exteriorly of the rotating drum. The rotating drum has at least one opening or notch in a magnetic recording medium-winding surface thereof. In order to restrain the deformation of the rotating drum during the rotation thereof, the center of gravity of the drum is disposed substantially in registry with the axis of rotation of the drum.
