Title: 광 디스크 드라이브 마이크로콘트롤러용 프로그램 코드를 갱신하는 방법 및 광 디스크 드라이브
IPC: G06F9/445
Filed: 1998-06-11
Abstract: 광 디스크 드라이브는, 마이크로콘트롤러의 형태를 갖는 시스템 제어기(1)와, 마이크로콘트롤러용 프로그램 코드를 기억하는 FLASH 메모리(22)를 구비한다. 상기한 FLASH 메모리는 2개의 영역으로 형성되는데, 제 1 영역은 코드를 변경할 수 없는 보호 영역이고, 제 2 영역은 마이크로콘트롤러가 갱신된 프로그램 코드를 기록할 수 있는 비보호 영역이다. 이러한 갱신된 코드는 인터페이스(28)를 통해 호스트 컴퓨터로부터 수신한다. 상기한 보호 영역과 마이크로콘트롤러의 ROM 내부에 있는 코드는, 호스트 컴퓨터에 프로그램 코드를 요구하여 그것을 수신하며 수신된 프로그램 코드를 FLASH 메모리의 비보호 영역에 기록하는 기본 기능을 수행할 수 있도록 하는데 충분한다. 이러한 구성은, 예를 들어 코드를 전송하는 동안 전원 차단이 발생할 때와 같이, 비보호 영역에 있는 코드가 파괴되는 경우에도 드라이브를 복구할 수 있도록 한다.

Abstract: Optical stabilisation system having a signal source (1) connected to a transmission line (2) and a noise source (3). The signal source (1) comprises a laser having a number of laser modes within a first wavelength band for generating an optical transmission signal (S). The noise source generates a narrow-band noise signal which is inserted into the transmission line via coupling means (5) and is injected into the laser of the signal source (1). The noise signal forces the laser to operate in a laser mode within the noise band. Via a power distributor (11), a portion of the noise signal can also be injected into a laser of a further signal source (9) for stabilisation in a laser mode within the same noise band. Any signals outside the noise band are removed from the transmission signal by a narrow-band filter (8). The stabilisation system is applied in passive optical networks for groupwise wavelength assignment to network terminals. <IMAGE>
