RECORDING HEAD, METHOD FOR MANUFACTURING RECORDING HEAD AND COMPOSITE HEAD AS WELL AS MAGNETIC RECORDING AND REPRODUCING DEVICE

摘要

PURPOSE: To firstly realize a recording head and composite head of low-reproduction noise even when a Co-Ni-Fe film and 45NiFe film are applied to the composite film, to provide the recording head which can effectively utilize the high saturation magnetization characteristic of the core material of high saturation magnetization and the Co-Ni-Fe film of 2T saturation magnetization by these films, to thirdly provide the recording head of high recording performance at a high frequency and the recording head of a narrow track width of high density recording, to provide the method for manufacturing the recording heads and composite heads described above and to provide a storage device for high-capacity and high-speed data transfer with the magnetic recording and reproducing device mounted with the recording and composite heads described above. CONSTITUTION: The magnetic head which is formed with a magnetic gap at one end of first and second magnetic cores facing each other and is provided with insulating coils between the first and second magnetic cores by magnetical coupling at the other end, in which the magnetic fluxes of the first magnetic cores magnetized by the same execute recording on the magnetic medium by the leakage from the recording gap. The recording head is characterized in that the distance from the front end of the recording gap proximate to the magnetic medium to a magnetical joint contact is < 20 μm.
