Abstract
본 발명은 디지탈데이타를 기록 및 재생하는 디지탈 기록재생장치 및 방법에 관한 것으로, 특히 데이타의 기록 환경과 재생환경의 변화에 따라 기록 및 재생을 최적으로 수행할 수 있도록 하는 것으로 입력 디지탈 데이타신호를 저장하는 제1메모리, 제1메모리에서 독출되는 데이타를 채널특성에 따라 변조하는 변조부, 변조부에서 변조된 기록신호를 소정의 크기로 증폭하여 기록헤드로 공급하는 제1증폭부, 기록매체상에 기록된 기록신호를 재생헤드를 이용하여 재생하여 소정크기로 증폭하는 제2증폭부, 제2증폭부에 의하여 증폭된 재생신호를 주파수특성등의 열화를 보상하기 위한 등화기, 등화기의 출력을 채널특성에 따라 복조하기 위한 복조부, 복조부에 의하여 복조된 신호를 저장하기 위한 제2메모리, 및 제1메모리와 제2메모리에 저장된 데이타를 비교하여 기록시에는 제1증폭부에서의 증폭정도를 조정하고 재생시에는 등화기에서의 신호보상을 조정하는 기록재생조정부를 포함한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital recording and reproducing apparatus and method for recording and reproducing digital data. In particular, the present invention provides a method for optimally performing recording and reproducing according to changes in the recording and reproducing environments of data. A first memory, a modulator for modulating the data read out from the first memory according to channel characteristics, a first amplifier for amplifying a recording signal modulated by the modulator to a predetermined size and supplying it to a recording head and a recording medium. A second amplifier for reproducing the recorded recording signal using a reproduction head and amplifying the predetermined signal to a predetermined size, and outputting an equalizer and an equalizer for compensating for degradation of a frequency characteristic, etc., of the reproduction signal amplified by the second amplifier. A demodulator for demodulating according to channel characteristics, a second memory for storing signals demodulated by the demodulator, and data stored in the first memory and the second memory. A comparison will be recorded when the recording and reproducing includes adjusting unit for adjusting the degree of amplification in the first amplifier, and has to adjust the compensation signal from the reproduction equalizer.
