US 6,715,123 B2 · Real-time recording system and real-time recording method

Abstract

A real-time recording system that decreases the load applied to a central processing unit, which controls recording. The recording system includes a memory for storing input data. An error correction circuit is connected to the memory for generating write data from the input data and storing the generated write data in the memory. A formatter circuit is connected to the memory and the error correction circuit for reading the write data stored in the memory and writing the read write data to the recording medium in real-time. The error correction and formatter circuits are controlled for the generation of the write data with the error correction circuit and the writing operation with the formatter circuit by a plurality of control signals. The control signals are transferred between the error correction circuit and the formatter circuit.
