    • The present invention enables a comprehensive evaluation from both of data read from a disk and a servo signal of a servo controller. The present invention provides a semiconductor integrated circuit mountable to a disk recording and reproducing drive, which comprises a signal processor of an RF signal read from a pickup, a servo controller responsive to a servo error signal read from the pickup, a memory controller, and an external interface. The memory controller is supplied with read data and a servo signal and stores the read data and the servo signal in a buffer memory according to a time division process. The read data and the servo signal stored in the buffer memory can be transferred to an external device via the external interface by the memory controller.
    • 本发明能够从从盘读取的数据和伺服控制器的伺服信号两者进行综合评估。 本发明提供一种可安装到盘记录和再现驱动器的半导体集成电路,其包括从拾取器读取的RF信号的信号处理器,响应于从拾取器读取的伺服误差信号的伺服控制器,存储器控制器和 一个外部接口。 存储器控制器被提供有读取数据和伺服信号,并且根据时分处理将读取的数据和伺服信号存储在缓冲存储器中。 存储在缓冲存储器中的读取数据和伺服信号可以由存储器控制器通过外部接口传送到外部设备。
