Abstract

This invention provides a recording and/or reproducing apparatus having a reproducing circuit for reproducing coded main information, and historical information, with respect to signal processing which was performed on the main information. An error correcting circuit corrects a code error in the main information. The reproducing circuit provides error correcting information with respect to the error correcting processing. A first constructing circuit constructs coded data based on the correcting information by concealing an error which cannot be corrected by said error correcting circuit. A decoding circuit decodes the main information provided by the first constructing circuit, and a second constructing circuit constructs decoded data by concealing the error, which cannot be corrected by the error correcting circuit, in the main data which has been decoded by the decoding circuit. The decoded data is constructed based on the historical information and the correcting information, thus preventing degradation of the signal and allowing a high quality image to be obtained.
