One terminal of a parallel resonance circuit 20A is connected to the connection midpoint P in the positive feedback loop to constitute an oscillation circuit. Then a high pass filter is formed in the positive feedback loop by the capacitor 35 of a proper capacitance and a low input resistance Ri of a common base TR 32. Thus, the feedback quantity of the positive feedback loop is increased as the frequency increases and nearly stable oscillation intensity is obtained over a wide frequency range such as fmax/fmin<=3.

Filed: 1989-06-27
Abstract: PURPOSE:To supress noise to increase S/N, to suppress generation of peak shift and to prevent attraction of a head to the medium by providing an insulating layer and an anodized aluminum layer between a magnetic layer and protective layer. CONSTITUTION:Since an anodized aluminum layer 31 has a rough surface, a protective layer formed on this anodized aluminum layer has proper roughness, which prevents attraction of a head to the magnetic recording medium. Namely, the insulation layer 30 and anodized aluminum layer 31 of column-like structure are formed between the magnetic layer 29 and protective layer 32, so that surface of the protective layer 32 has proper roughness and the magnetic layer has small roughness. Thereby, noise caused by the magnetic layer 29 itself can be supressed to improve S/N. Moreover, peak shift can be supressed and adsorption of a head to the medium can be also prevented.
