摘要： A magnetic head having an upper head and a lower head disposed opposite to each other and capable of simultaneously reading information from or writing information in both sides of a magnetic disc inserted therein. The upper head is fixed to a wingable arm at correct vertical position and inclination, while the lower head is mounted through a gimbals spring on a carriage which is slidable along a guide rod or guide rods in the radial direction of the magnetic disc. Since the upper head is positioned correctly and the surface thereof facing the lower head serves as a datum surface, the inclination of the lower head need not be adjusted in assembling the magnetic head, and thereby the process for assembling the magnetic head is remarkably simplified.
摘要翻译：一种磁头，其具有彼此相对设置的上磁头和下磁头，并且能够同时从插入其中的磁盘的两侧读取信息或写入信息。上头部以正确的垂直位置和倾斜度固定到可机翼臂上，而下头部通过万向弹簧安装在滑架上，托架可沿导向杆或导杆沿着磁盘的径向方向滑动。由于上部头部正确定位并且其面向下部头部的表面用作基准面，所以在组装磁头时不需要调整下部头部的倾斜度，从而显着简化了用于组装磁头的过程。

摘要： A disk recording-reproducing device having a carriage with a read/write head, a screw shaft to shift the carriage with an engaging element through coupling between a spiral groove of the screw shaft and the engaging element, and a stepping motor to rotate the screw shaft. The spiral groove is composed of a number of groove portions each with a straight bottom whose angle of lead is substantially zero degree that are displaced successively, circumferentially and axially. Preferably, the screw shaft has plane portions for its positioning, and a rotor of the stepping motor has magnetization points being set correspondingly to the lines of the groove portions.

摘要： An information recording disk includes detection regions used to confirm presence or absence of written signals, read/write regions available for signal writing and write-project regions which reject signal writing. Regions where the detection regions and read/write regions overlap each other are originally provided with discriminating signals to distinguish these regions from at least the other regions. The write protect regions are distinguished from the read/write regions, referring to information detected by a head assembly.

摘要： A magnetic head assembly including a carriage which carries thereon a first magnetic head for information writing and reading to and from one side of a disc-like magnetic recording medium, and a hold case which carries thereon a second magnetic head for information writing and reading to and from the other side of the magnetic recording medium, the second magnetic head being disposed in a position opposed to the first magnetic head, the hold case being connected to the carriage through hinge means rotatably to a certain degree relative to the carriage, and the magnetic head assembly being reciprocated in a radial direction of the magnetic recording medium. The first magnetic head is mounted on the carriage through a gimbal spring which is formed rotatably to a certain degree with respect to biaxial hinge portions, and the second magnetic head is mounted on the hold case through a spring plate which is formed rotatably to a certain degree with respect to a uniaxial hinge portion. The hold case is urged toward the carriage on the side of the hinge means rotatably to a certain degree relative to the carriage.
