Abstract
The information recording unit has a memory for firstly storing data, a record medium for intermittently recording the stored data in the memory, a record means for recording the data on the record medium, and a valid-data decision means for determining whether the recorded data is valid. The record means records the data in at least two different areas on the record medium, and the decision determines one valid data among the recorded data in the different areas. The unit includes a record control means for controlling the record means. The record control means provides a control command for the record means to record a predetermined quantity of data stored in the memory at a first recording location on the record medium and also provides a control command for the record means to read the predetermined quantity of the data at least one recording location different from the first recording location after the predetermined quantity of the data is recorded at the first recording location.
