The magnetic head is equipped with a recording head where a lower tip magnetic pole and an upper tip magnetic pole are formed facing one another on both sides of a write gap and a coil is disposed on a rear side of the lower magnetic pole. The lower tip magnetic pole is provided with an apex part by forming the surface on the rear side on which the coil is disposed as an inclined surface, and an insulating layer that covers the coil is formed to the rear of the lower tip magnetic pole.

摘要： A method of manufacturing a thin-film magnetic head is capable of planarizing and forming the upper surface of a main magnetic pole with high precision, of forming a trailing gap with a precise form, and of efficiently and precisely forming side shields and a trailing shield. A stopper layer is formed so as to cover a magnetic pole and so that a thickness thereof at positions on both sides of the magnetic pole is a predetermined side shield gap width. After a resist layer has been formed so that a thickness thereof at positions on both sides of the magnetic pole is a predetermined side shield width, an insulating layer is formed thereupon and then lapping according to a CMP process is carried out until the stopper layer becomes exposed. After this, the stopper layer is removed by dry etching until the upper surface of the magnetic pole becomes exposed, and then the upper surface of the magnetic pole is lapped by a CMP process until the surface is planarized. Next, the resist layer is removed and the stopper layer that becomes exposed due to such removal is also removed to form the trailing shield and the side shields.

摘要： An amplifier includes a first voltage follower including P-type MOS transistors and a second voltage follower including N-type MOS transistors. The first voltage follower amplifies without being saturated even if an input signal voltage approaches a level of a power supply voltage when the input signal voltage is at least equal to a bias voltage, but does not amplify when the input voltage is less than the bias voltage. A second voltage follower of the amplifier amplifies without being saturated even if an input signal voltage approaches a ground potential when the input signal voltage is less than the bias voltage, but does not amplify when the input voltage is at least equal to the bias voltage.

The method includes a step of forming an insulating film on a substrate surface to cover a surface of a metal layer that has a predetermined pattern and then forming a stopper film on a surface of the insulating film; a step of forming a resist pattern that exposes only bulging parts of the insulating film that cover the metal layer and then removing the stopper film from the surface of the bulging parts to form a stopper layer on a surface of the insulating film covered by the resist pattern; a grinding step of grinding the surface of the substrate to grind the bulging parts as far as a position regulated by the stopper layer; and a step of removing the stopper layer from the surface of the insulating film and then carrying out finish-up grinding on the surface of the substrate.

摘要： A clamp control circuit outputs a clamp control signal after a delay of a predetermined time if a digital video signal is detected. A sampling circuit that extracts sampling data of a pedestal level from a luminance corrected signal based on a clamp pulse at a timing of the back porch. A data averaging circuit calculates an average of the sampling data of the pedestal level. A data holding circuit holds a difference between the average and a digital signal processing reference level when the clamp control signal is output and also when the clamp control signal is not output. A level correction circuit corrects a level of the luminance signal based on the difference held by the data holding circuit and outputs the corrected luminance signal.
