摘要： A disk cartridge has a case including a first planar portion and a second planar portion which are disposed opposite to each other with a given spacing therebetween, and a plurality of walls which join the first planar portion and the second planar portion together. The case contains an information carrying disk in a rotatable manner and has an opening formed in one of the walls through which the disk can be inserted or removed. The disk cartridge has a lid mounted on the case for opening or closing the opening. The lid is formed so that an outer surface of the lid is located inside an outer surface of the wall in which the opening is formed.

摘要： A turntable is a table mounted to a shaft (4) of a spindle motor and the turntable supports a laminated disc thereon and drives the disc in rotation. The laminated disc includes a lower disc and an upper disc stacked on the lower disc, and is supported on a disc-supporting surface. When the disc is loaded on the turntable, a fitting member fits into the center hole of the laminated disc for centering the laminated disc with respect to the shaft. The fitting member fits the center hole of the lower disc when the laminated disc is supported on said disc-supporting surface. The turntable may include a tapered member which guides the laminated disc to the disc-supporting surface. The laminated disc includes lower and upper discs each having an edge which defines the center hole. The corners of the edges are cut away along a circumference of the center hole. The upper and lower discs are placed together so that the cut-away corner directly face each other.
摘要翻译：转台是安装在主轴电动机的轴（4）上的工作台，并且转台在其上支撑层压盘，并驱动盘旋转。层压盘包括下盘和堆叠在下盘上的上盘，并且支撑在盘支撑表面上。当盘被装载在转盘上时，配合构件装配在层压盘的中心孔中，用于使层压盘相对于轴定心。当层压盘被支撑在所述盘支撑表面上时，配合构件适合于下盘的中心孔。转台可以包括锥形构件，其将层叠的盘引导到盘支撑表面。层压盘包括每个具有限定中心孔的边缘的下盘和上盘。沿着中心孔的圆周切割边缘的角。上下盘被放置在一起，使得切割角直接面对彼此。

摘要： A magnetic recorder/reproducer converts two-channel analog signals into digital signals by a sample-and-hold/A-D converter circuit (3) and controls addresses in a memory circuit (4) by a memory address control circuit (5), to distribute the digital signals into odd sample groups and even sample groups per each channel for arraying the odd sample groups and the even sample groups of the same channel in alternate scanning intervals, thereby to write the same in the memory circuit so that the odd samples and the even samples of the same channel are arrayed in positions separated from each other along the direction of scanning by rotary heads (10, 11). The digital signals thus permutated are modulated by a modulation circuit (7), to be recorded in a magnetic tape by the rotary heads. The digital signals reproduced by the rotary heads are demodulated by a demodulation circuit (14), to be stored in a memory circuit (15). A memory address control circuit (16) controls addresses so as to permutate samples of the reproduced digital signals stored in the memory circuit to be in the original array thereof. The reproduced digital signals read from the memory circuit are converted into analog signals by a D-A converter (18), to be outputted through a low-pass filter (19).
