Video data recording and playing device

摘要

A video data recording and playing device includes: a first recording unit adapted to record and read data on and from a first recording medium; a second recording unit adapted to record and read data on and from a second recording medium; and a control unit operatively connected to the first and second recording units and configured to selectively start and finish the recording by the first and second recording units. The first recording unit is further configured to detect a recording error that is due to a defect in the first recording medium and occurs while the first recording unit records data on the first recording medium. The control unit is configured to start recording data with the second recording unit on the second recording medium when the first recording unit detects a recording error while the first recording unit records the data on the first recording medium.
