    • 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。

    • The floppy disc drive interface circuit comprises a floppy disc drive and a voltage frequency oscillator outputting a read data signal and a window signal based on a read data pulse generated by the floppy disc drive. The fundamental frequency signal from a generator and the window signal from the voltage frequency oscillator are received and a pulse width of the window signal is measured. A mode signal is output representing a set data transfer rate of the read data signal. A window gate signal is generated based on a measurement value of the window signal from the pulse width measurer and a data transfer rate represented by the mode signal from the mode signal output.
    • 软盘驱动器接口电路包括软盘驱动器和输出读取数据信号的电压频率振荡器和基于由软盘驱动器产生的读取数据脉冲的窗口信号。 来自发生器的基频信号和来自电压频率振荡器的窗口信号被接收并且测量窗口信号的脉冲宽度。 输出表示读取数据信号的设定数据传送速率的模式信号。 基于来自脉冲宽度测量器的窗口信号的测量值和由模式信号输出的模式信号表示的数据传输速率,生成窗口门信号。

    • The magnetic head mounted on a floppy disk driver comprises a reading and erasing head section (1) having a first gap (3) of a give length and a recording hed section (2) having a second gap (4). A pair of side section (2) having a second gap (4). A pair of side portions joined to opposite ends of a middle portion of the first gap are straight with a length equal to the length of the second gap. Both side portions of the first gap are symmetrically bent at an angle (theta) towards the recording head section. The angle is within arange from one degree to sixty degrees. An overlapped recording portion of information is not formed on a diskette.
    • 安装在软盘驱动器上的磁头包括具有给定长度的第一间隙(3)和具有第二间隙(4)的记录套管部分(2)的读取和擦除头部分(1)。 具有第二间隙(4)的一对侧部(2)。 连接到第一间隙的中间部分的相对端的一对侧部是直的,其长度等于第二间隙的长度。 第一间隙的两个侧面部分以朝向记录头部分的角度(θ)对称地弯曲。 角度在一度到六十度之间。 信息的重叠记录部分不形成在磁盘上。
