    • A method for detecting a defective sector on a recording medium in a method for recording and/or reproducing data for the signal recording medium. A read gate is opened to reproduce data from a data field at a pre-set timing derived from a timing reference signal obtained on detecting a servo timing mark recorded in a servo field. If the timing reference signal has not been detected with success, the read gate is opened at a timing obtained based on a detection signal of a previously detected servo timing mark to reproduce the data from the data field. In detecting the defective sector, the state of deviation between the timing of opening the read gate and the data field is detected to detect the defective sector of the disc.
    • 一种用于在用于记录和/或再现用于信号记录介质的数据的方法中的用于检测记录介质上的缺陷扇区的方法。 一个读门被打开,以从在检测到伺服字段中记录的伺服定时标记获得的定时参考信号得到的预定定时从数据字段再现数据。 如果定时参考信号未成功检测到,则读门在基于先前检测到的伺服定时标记的检测信号获得的定时被打开,以从数据场再现数据。 在检测到缺陷扇区时,检测打开读取门的时间与数据场之间的偏差状态,以检测盘的缺陷扇区。

    • A main unit includes a file manager for inputting and outputting data files and an add-on driver for performing an extended function. The file manager and the add-on driver are connected to a first serial interface through respective protocol circuits. Input terminals of the first serial interface are connected to predetermined contacts of a connecting section, respectively. A power supply supplies power VCC and VSS to predetermined contacts in the connecting section. Data is exchanged with a register and a page buffer through a second serial interface provided in an electronic device. A read area at an arbitrary address in the register is used as an area in which a current value is written. A write area at the same address is used as an area in which a control signal is written. For example, a current suppliability bit and a function enabled bit are provided.
    • 主单元包括用于输入和输出数据文件的文件管理器和用于执行扩展功能的附加驱动程序。 文件管理器和附加驱动程序通过各自的协议电路连接到第一个串行接口。 第一串行接口的输入端分别连接到连接部分的预定触点。 电源为连接部分中的预定触点提供电源VCC和VSS。 数据通过设置在电子设备中的第二串行接口与寄存器和页缓冲器交换。 寄存器中任意地址的读取区域被用作写入当前值的区域。 使用相同地址的写入区域作为写入控制信号的区域。 例如,提供电流供应位和功能使能位。

    • An electronic device includes a serial interface which exchanges data with a memory register and a first data buffer. In accordance with a setting which is written in the memory register, data in the first data buffer is exchanged with a memory through a memory controller. The serial interface exchanges data with an add-on register and a second data buffer. In accordance with a setting which is written in the add-on register, data in the second data buffer is exchanged with an add-on unit through an add-on controller. The add-on unit is connected to an external LAN or the like. Part of the setting data written in the memory register and the add-on register is determined from the add-on unit by a system control circuit. In accordance with the determination, a function to be executed by the electronic device is changed.
