ABSTRACT:
An apparatus serving as a digital videocassette recorder (VCR) for recording analog video and audio signals as digital signals. The apparatus serves also as a digital data storage drive. The digital VCR and the storage drive share common circuitry and a common magnetic recording medium. This reduces the cost and enhances the efficiency at which tracks are used. The apparatus has a large storage capacity. The apparatus divides input digital data into two parts and performs error correction encoding for each of these two data parts to form sync blocks. These sync blocks are recorded in an audio signal recording area and a video signal recording area, respectively, on the recording medium. Error correction codes used during reading of digital data are the same as those used during recording of video and audio signals. The same track structure and the same sync block structure are used for these two modes of operation.
