A layout capable of placing a circuit constituted by a plurality of transistors in a small-with region is automatically formed. A search section inputs data on a circuit and makes a search for a set of routes formed so that passage through any one of the transistors occurs only one time and so that the combination of routes in one set can cover the entire circuit network. An extraction section extracts a set of routes having the smallest number of routes in sets of route found by searching. A width determination section determines the layout width from the widths of source and drain electrodes of each transistor, the width of the region between the source and drain electrodes, the width of the region between some of the adjacent pairs of the transistors not combined into a common electrode, the number of transistors, and the smallest number of routes. A layout determination section forms information on a layout in which all the source, drain and gate electrodes of the transistor included in the circuit are placed in a small-width region having the determined width.

A charge pump-type booster circuit can reduce numbers of switches and capacitors. The charge pump-type booster circuit has a first electronic switch and a second switch connecting a high potential terminal and a low potential terminal of a charge capacitor are connected to a not grounded terminal of a first output capacitor connected to the ground at one side. These electronic switches are not conducted simultaneously. A third electronic switch is provided for connecting the high potential terminal of the charge capacitor and a not grounded terminal of a second output capacitor grounded at one side.

A magnetic head and a manufacturing method of the magnetic head and a magnetic recording and reproducing apparatus used this head, in which the following problem is solved, are provided. A plated film realizing large saturation magnetization Bs about 2T can not realize a high resistivity at the same time, therefore, when this plated film is applied to a magnetic head, the high frequency characteristic is deteriorated.

A layout for placing a circuit having a plurality of transistors in a small-width region. A search section inputs data on a circuit and searches for a set of routes formed so that passage through a transistor occurs only one time and so that the combination of routes covers the entire circuit network. An extraction section extracts a set of routes having the smallest number of routes. A width determination section determines the layout width from source and drain electrodes, the region between the source and drain electrodes, the region between adjacent pairs of the transistors not combined into a common electrode, the number of transistors, and the smallest number of routes. A layout determination section forms a layout in which the source, drain and gate electrodes of the transistor included in the circuit are placed in a small-width region.
