    • A magnetic playback apparatus and method with which a PLL phase-locked to played-back data operates stably even when the magnetic tape on which the data is recorded is transported at a high speed of several hundred times the recording speed. During high-speed playback of a magnetic tape, the speed of the magnetic tape is detected and using this tape speed information the free-run frequency of a PLL 2 is corrected in correspondence with the azimuth angles of magnetic heads HO, HE. The rotational period of a drum servo 3 is also corrected using the tape speed information.
    • 即使当其上记录有数据的磁带被以记录速度的几百倍的高速传送时,也可以稳定地操作,即PLL被锁相到重放数据的磁性重放设备和方法。 在磁带的高速重放期间,检测磁带的速度,并且使用该磁带速度信息,根据磁头110,HE的方位角来校正PLL 2的自由运行频率。 鼓伺服机构3的旋转周期也使用磁带速度信息进行校正。

    • Data which is greater in capacity than the prior arts is recorded and reproduced on and from a low-capacity recording medium. In a large-capacity flexible disk device having head sliders (4) loaded with a low-capacity magnetic head and a high-capacity magnetic head, a control means such as a CPU 14 and the like for controlling the low-capacity magnetic head and the high-capacity magnetic head is provided so that a high-capacity track format is written in a low-capacity recording medium (1) by the low-capacity magnetic head to record information, and the information recorded on the low-capacity recording medium (1) in a high-capacity track format is reproduced by means of the high-capacity magnetic head.
    • 与现有技术相比容量更大的数据在低容量记录介质上记录和再现。 在具有装载有低容量磁头和高容量磁头的磁头滑块(4)的大容量软盘装置中,用于控制低容量磁头的诸如CPU14等的控制装置和 提供高容量磁头,使得通过低容量磁头将高容量磁道格式写入低容量记录介质(1)中以记录信息,并且记录在低容量记录介质 (1)通过高容量磁头再现高容量磁道格式。

    • In order to easily conduct channel switching and inter-channel mixing at the time of editorial operation without connecting an external device for channel switching or inter-channel mixing, the lap top type video recording and reproducing device includes two built-in audio two channel type video tape recorders, a built-in editorial means for editing between the two video tape recorders, and two audio monitors in one body. The device further includes, a signal selecting circuit for selecting either of a first state where the two channel audio signals reproduced by the video tape recorder are outputted from the same channels, a second state where the reproduced two channel audio signals are outputted from the opposite channels after channel switching, and a third state where the reproduced two channel audio signals are mixed to output the same signals from the both channels, and an input switching circuit for supplying output signals from the signal selecting circuit to the video tape recorder in place of two channel audio input signals inputted from the outside.
    • 为了在编辑操作时容易地进行频道切换和频道间混合而不连接用于频道切换或频道间混合的外部装置,膝上型视频记录和再现装置包括两个内置音频双声道类型 磁带录像机,用于在两台磁带录像机之间进行编辑的内置编辑工具,以及一个机身中的两个音频监视器。 该装置还包括:信号选择电路,用于选择第一状态和第二状态中的任何一个,在第一状态中由录像机重放的两个声道音频信号是从相同的声道输出的,第二个状态是从相反的一个频道输出重放的两个声道音频信号 频道切换之后的频道以及第二状态,其中再现的两声道音频信号被混合以输出来自两声道的相同信号,以及输入切换电路,用于将来自信号选择电路的输出信号提供给录像机以代替 从外部输入的两路音频输入信号。
