A data recorder for recording data on a recording medium includes a data storage part, an error detection part, an erasure part, a determination part, and a recovery part. When the error detection part detects a data transfer error, the determination part determines whether data corresponding to the data erased by the erasure part is stored in the data storage part. When the determination part determines that the corresponding data is stored in the data storage part, a recovery part recovers the erased data on the recording medium based on the stored data.
