A method for recording serial data in successive data blocks on a recording medium and verifying the accuracy of the recording is disclosed, together with apparatus for effecting the method. In the method, serial data received on line 26 is divided into blocks by temporary storage in BuFERA 61 or BuFERB 62 until the temporary store is full. A characteristic of the data block is stored in CHKSUM 60 and compared with a reference to determine the validity of the received data. A value related to that in CHKSUM is stored in CHEKIN 59. The data block is transmitted to transducer 33 and recorded on tape 30. A characteristic is stored in CHEKWR 63 and compared with CHEKIN 59 to verify the accuracy of the recording. The tape 30 is then rewound and the data block is read. A characteristic of the read data block is stored in CHEKRD 64. The values in CHEKWR, CHEKIN and CHEKRD are compared to verify the recorded data block. <IMAGE> |
