摘要： Unlike conventional disk drives, a disk drive of the invention is capable of loading a plurality of different types of disks at the same time, and has the capability of protecting a disk sensitive to contamination, such as a RAM disk, from contamination. A plurality of trays are placed in a disk package which is loaded into a disk drive. Different types of disks may be placed on the respective trays. In the package, there is provided a first locking mechanism for locking all trays. This first locking mechanism can be unlocked by a manual operation. There is also provided a second locking mechanism which locks only those trays on which RAM disks or the like are placed so that the RAM disks are prevented from being taken out. In the main unit of the disk drive, there is provided an unlocking member for unlocking both the first and second locking mechanisms.

摘要： An error component such as an eccentricity implicated in an encoder itself is superimposed upon a detected value from an FG due to an assembly error of assemblies themselves and in the manufacturing process. As a result, a speed could not be controlled with a high accuracy and wow and flatter could not be reduced. A tape speed (TSS) signal detected and corrected from the tape transport by FG and PG is inputted into a PLL loop within a data controller (TBC) of a reproducing system. A reproduced signal is converted by an A/D converter in response to a reference clock generated therein and this data is temporarily stored in an FIFO. When this data is reconverted by a D/A converter into an analog signal, if this data is sequentially converted at a timing of an absolute control clock of a quartz oscillator, then it is possible to eliminate the error component superimposed upon the head reproduced signal. Thus, from a theory standpoint, it becomes possible to erase the wow and flatter of the drive mechanism system from the head reproduced signal.
摘要翻译：由于组装本身的组装误差和制造过程中，与编码器本身相关的诸如偏心之类的错误组件叠加在来自FG的检测值上。结果，无法以高精度控制速度，并且不能减少平坦度。通过FG和PG从磁带传输中检测和校正的磁带速度（TSS）信号被输入到再现系统的数据控制器（TBC）内的PLL环路中。再现信号由A / D转换器响应于其中产生的参考时钟转换，并且该数据被临时存储在FIFO中。当该数据被D / A转换器转换为模拟信号时，如果在石英振荡器的绝对控制时钟的定时将该数据顺序地转换，则可以消除叠加在磁头再生信号上的误差分量。因此，从理论的观点来看，可以从磁头重放信号中擦除驱动机构系统的笨拙和平坦。

摘要： A driving device in which when a cartridge is inserted with a correct orientation, a retainer protrusion of a drawing-in member engages a retainer recess of the cartridge, so that a sliding shaft of the drawing-in member slides along a guide surface to draw in the cartridge. When the cartridge is inserted with a reversed orientation, the drawing-in member is pushed sideways, so that the sliding shaft slides along a relief guide portion at the exterior side of the guide plate, causing the drawing-in member to be driven in the X1 direction. Since the drawing-in member is driven along the relief guide portion, locking of the mechanism does not occur. Accordingly, it is possible to prevent locking of a mechanism, which occurs when the cartridge is inserted with a wrong orientation, and the drawing-in member, which is not retained by the cartridge, is driven in the drawing-in direction, in a disk device in which a drawing-in member is used to draw in a cartridge of, for example, a mini-disk.
摘要翻译：一种驱动装置，其中当盒以正确的方向插入时，拉入构件的保持器突起与卡盘的保持器凹部接合，使得拉入构件的滑动轴沿着引导表面滑动以绘制在墨盒中。当墨盒以相反的方向插入时，引入构件被侧向推动，使得滑动轴沿着引导板的外侧的释放引导部分滑动，使得引入构件被驱动在 X1方向。由于引导构件沿着释放引导部被驱动，所以不会发生机构的锁定。因此，可以防止当盒以错误的方向插入时发生的机构的锁定，并且未被盒保持的引入构件沿着拉出方向被驱动磁盘装置，其中使用绘图构件来绘制例如小型盘的盒。

A first lock mechanism for locking all the trays is arranged in the package, and a locking operation of this lock mechanism can be released by a manual operation. A second lock mechanism is designed to be able to lock only a tray on which a RAM disk or the like is placed and to prevent the RAM disk or the like from being removed. However, when an projection portion of the tray is deformed, the tray can be removed.

摘要： An analog reproduced output can be processed by a digital system circuit in a digital and analog data processing apparatus. An analog output reproduced from a medium on which analog signals are recorded is converted into digital signals by an (A/D) analog to digital converter of a digital recording and reproducing system. These signals are divided signals corresponding to predetermined frequency bands by sub-band filters. The signals are input to a (DSP) digital signal processing section and an (ECC) error correction coding section. An frequency characteristic adjustment operation and an interpolation operation are performed digitally under the control of a controller. Then, for example, the signals are converted by a (D/A) digital to analog converter and output.

摘要： A head height adjustment construction in a magnetic recording and reproducing apparatus with a rotary cylinder for use in a VTR, for example, includes a lower fixed drum, an upper rotary drum axially spaced from and rotatable with respect to the lower fixed drum, the upper rotary drum having a tapered surface slanted upwardly in a radially outward direction thereof, a head attachment plate having one end mounted on the upper rotary drum and supporting a head on an opposite end thereof, and an adjustment screw threaded in the upper rotary drum and held against the head attachment plate. When the height of the head is to be adjusted, the adjustment screw is turned about its own axis for spacing the opposite end of the head attachment plate away from the tapered surface. After the head height has been adjusted, a surface of the head which is held in sliding contact with a magnetic tape is directed upwardly toward a plane in which the upper rotary drum is rotatable.
