PROBLEM TO BE SOLVED: To previously prevent the disturbance of output owing to the damage of data by compressing, encoding and recording input data at a first bit rate and a second bit rate lower than the first bit rate. SOLUTION: A high bit rate compression device 2 compresses/encodes image data SIN at the high bit rate and a low bit rate compression device 3 compresses and encodes data SIN at the low bit rate. High bit rate compressed picture data S1 and low bit rate compressed picture data S2 are outputted to a controller 4 and HDD 5. The controller 4 allocates a write address for writing respective pieces of data based on the bit rate of compressed image data S1 and S2 and it is outputted to HDD 5 as a control signal S3. HDD 5 records compressed image data S1 and S2 in different areas on a hard disk. When compressed image data S1 is damaged at the time of reproduction, compressed image data S2 is expanded and decoded.
