摘要： A magnetic recording apparatus of a helical scanning system comprises a rotary cylinder (13), recording heads (A and B) and an erase head (10) attached to slightly project from a rotating surface (13a) of the cylinder (13). The rotary erase head (10) has a gap (4) comprising a ferrite core half (1) and a Sendust film (3) formed on a ferrite core half (2) opposed to the ferrite core half (1) and having a larger saturation magnetic flux density. In addition, the recording heads (A and B) and the rotary erase head (10) are attached on the rotary cylinder (13) so that an end (P1) located forward with respect to the tape travelling direction (11) of the Sendust film (3) may trace the backward side with respect to the tape travelling direction (11), apart by a distance which is a half of the gap length of the rotary erase head (10), as compared with a forward end (Q) of a recorded track pattern ( 15a) formed on a tape (14) by the recording head (A) scanning immediately after erasing by the rotary erase head (10).

摘要： A magnetic head has a pair of magnetic core halves opposed to each other with a non-magnetic material posed therebetween to form a magnetic gap, which head includes a pair of magnetic core halves, a first ferromagnetic metal thin film and a second ferromagnetic metal thin film. The magnetic core halves are formed of ferromagnetic oxide such as Mn-Zn ferrite, and they have opposing surfaces opposed to each other to provide the magnetic gap. The first ferromagnetic metal thin film formed of Fe-Si-Al alloy is formed at least on one of the opposing surfaces. The second ferromagnetic metal thin film formed of Fe-Si-Al alloy having different constituent ratio from the first ferromagnetic metal thin film is formed between the magnetic gap and the first ferromagnetic metal thin film. The flux density of the second ferromagnetic metal thin film induced when a magnetic field of 1.2K oersted is applied exceeds 1000 gauss. The ratio of the saturation flux density of the second ferromagnetic metal thin film to that of the first ferromagnetic metal thin film is not higher than 0.6. The self recording reproducing capability of the magnetic head is not degraded in the high frequency region, and the self recording reproducing capability in the low frequency region is increased.
