Abstract
Reproducing heads reproduce signals from a tape in advance of recording heads for a time period equivalent to a system delay. An ECC decoder corrects an error of a signal received from each reproducing head. A BRR decoder decompresses and decodes the signal received from the ECC decoder. A concealing circuit interpolates the signal received from the BRR decoder. An output signal of the concealing circuit is sent back to a selector of the recording system. The selector switches between a signal received from an input terminal and the reproduced signal at the end of each field. An intra-field encoding process or an intra-frame encoding process can be selected as an compressing and encoding process. Information that represents the selected encoding process is recorded on the tape.
