Abstract
CD-ROM 드라이브가 개신된다.The CD-ROM drive is rewound.
본 발명의 CD-ROM 드라이브는 디스크를 회전시키기 위한 스핀들 모터와, 상기 디스크에 기록된 정보를 읽어들이는 광픽업 등을 가지는 기구부와, 시스템을 전체적으로 제어하는 마이크로컴퓨터와, 상기 디스크의 정선 속도 제어를 위한 스핀들 서보 제어에 관여하는 DSP와, 상기 광픽업의 포커스, 트랙킹 및 슬레드 서보 제어에 관여하는 SSP와, 소정 펌웨어나 데이터를 저장하기 위한 ROM 등을 가지는 제어회로부를 구비하는 CD-ROM 드라이브에 있어서, 상기 제어회로부에는 상기 마이크로컴퓨터로부터 소정의 데이터나 프로그램을 다운로딩할 수 있는 플래쉬 메모리가 설치된다.The CD-ROM drive of the present invention includes a mechanism having a spindle motor for rotating a disk, an optical pickup for reading information recorded on the disk, a microcomputer for controlling the system as a whole, A CDP-ROM drive having a control circuit part having a ROM for storing predetermined firmware and data, and a control part for storing predetermined firmware and data, a DSP involved in spindle servo control for controlling the focus, tracking and sled servo control of the optical pickup, The control circuit unit is provided with a flash memory capable of downloading predetermined data or a program from the microcomputer.
이와 같은 본 발명의 CD-ROM 드라이브는 플래쉬 메모리를 이용하여 교체될 펌웨어를 용이하게 다운로드 할 수 있으므로 종래와 같이 기기를 분해하지 않고도 펌웨어를 용이하게 교체할 수 있는 장점이 있다.Since the CD-ROM drive of the present invention can easily download the firmware to be replaced by using the flash memory, there is an advantage that the firmware can be easily replaced without disassembling the device as in the prior art.
