摘要：An information verifying apparatus for verifying information recorded on arecording medium. One unit of information input is recorded on a storage medium and isretrieved from the storage medium. A buffer memory stores the one unit of informationinput, the one unit of information stored in the buffer memory being the same as the oneunit of information recorded on the storage medium. An output controller outputs theretrieved information and controls the timing of output of the retrieved information. Acomparator compares the information from the buffer memory with the informationfrom the output controller. Since the information is verified using a buffer memory andon output controller, verification can be quickly performed without the use of a largequantity of memory.
