摘要： PURPOSE:To make a step motor compact and make fine adjustment and mounting accuracy unnecessary when mounting a position detector by providing within a step motor a built-in position detector capable of detecting the moving position of the step motor by signals from an optical element. CONSTITUTION:A movable portion 27 is installed on a fixed portion 26 at the position limited by travel supporting mechanisms 28 of a linear step motor. In the fixed portion 27, slits 38 having the same accuracy and the same pitch as those of magnetic pole tooth 36 are provided at the central portion. An illumination source 40 is formed above the slits 38 of the movable portion 27, and light receiving sensor 41 is attached below slits 39 attached to a magnetic thin plate 34 at the fixed portion 26. When power is applied to a drive coil 32 and the movable portion 27 moves, a light beam from a light emitting element 40 installed at the movable portion 27 passes through the slits 38, the amount of light incident onto the light receiving sensor 41 located at the fixed portion 26 changes depending on the degree of overlap with the slits 39 of the fixed portions 26, and signals synchronized with the operation of the movable portion 27 are obtained. These signals are used for the closed loop control of the step motor.

摘要： PROBLEM TO BE SOLVED: To enable a more information quantity to be recorded by converting inputted recording information into recording codes with a prescribed system, selecting a magnetization having a first polarity, a magnetization having the polarity reverse to that of the magnetization having the first polarity and the magnetization of an AC erasion in accordance with the recording codes and recording the recording codes on a magnetic medium while making recording currents made to correspond to magnetic characteristics having selected magnetism flow through a magnetic head. SOLUTION: In the case of recording information, inputted information A are demarcated into information for every three bits in an information converting and recording circuit to be converted into recording codes B based on a comparison table. Then, recording currents corresponding to the recording codes B are made to flow through the magnetic heads from the information converting and recording circuit. +s, -s and 0s of the recording codes B are respectively made to be positive currents, negative current and currents of AC erase. Thus, three bits of the recording information are recorded with two recording codes by converting information equivalent to three bits of binary recording information A into information equivalent to two codes of ternary recording codes B in this manner. That is, 1.5-fold information is recorded in the same area or the same time.
