Abstract: PURPOSE:To record and reproduce to and from a recording medium whose disk diameter is small with high track density, by forming an erasing gap of an erasing head core by a high magnetic permeability thin film and a high magnetic permeability bulk material. CONSTITUTION:An I-bar of an erasing core is constituted of a high magnetic permeability thin film instead of a bulk material, and a high magnetic permeability thin film 15 is formed to about 1mum-50mum film thickness by means of spattering, vapor-deposition, etc. on a non-magnetic supporting body 13. According to such a constitution, it can be considered that the I-bar of the erasing core does not exist, therefore, even if a distance between a recording and reproducing gap and an erasing gap becomes small, there is room for placing a head core, and a saturation magnetization of the high magnetic permeability thin film 15 is remarkably larger than a saturation magnetization of ferrite, therefore, a recording medium of a high coercive force can also be erased exactly, the erasing capacity is also high, and also it can cope enough with converting a disk to a small diameter.

Abstract: PURPOSE:To obtain a magnetic head for vertical magnetic recording which has high practical performance, by carrying out the recording with a magnetic pole core consisting of a single or plural thin films of high permeability and then reproducing with a part of said magnetic pole core. CONSTITUTION:Thin films 12, 13 and 14 of high permeability are patterned on a nonmagnetic substrate, and a thin film coil 15 is wound around the tip area of the film 12. A coil 16 is wound totally around the films 12-14 at the rear part. The recording is carried out by exciting simultaneously film 12-14 entirely by the coil 16. The recording width of these films are set at T12+T13+T14 if each recording truck width is set at T12, T13 and T14 respectively. In this case, the gaps between films 12 and 13 as well as 12 and 14 are set at the value equivalent to the spread of the recording width to obtain an even width as a whole. While the reproduction is performed by detecting the change of a magnetic flux passing through the film 12 by the coil 15. The reproducing track width is set at T12. A sufficient gap is secured between the film 12 and the coil 15 as well as films 13 and 14 at the position distant away from the head tip part in order to avoid the interference between films 13 and 14. The interchangeability of data is assured despite an off-track generated between films 13 and 14.
