Abstract
In a facsimile apparatus having a magnetic tape recording apparatus for data storage and a buffer memory for data transfer to and from the recording apparatus, with the data being temporarily held in the buffer memory as respective blocks in a set of records, a synchronizing signal is inserted at the start of each recorded block of data, and the synchronizing signals are detected subsequently during playback of the recorded data. During playback, a buffer memory address generating circuit which specifies respective records and intra-record addresses for writing the playback data into the buffer memory, is reset to either the initial address of the current record or the initial address of the succeeding record each time a synchronizing signal is detected, in accordance with the position where the detection occurs within the addresses of the current record. The effects of an error in the playback data can thereby be limited to the data block in which the error occurs, without propogating to subsequent blocks.
