Abstract
A recording apparatus records information, which is continuously inputted from the external, onto a record medium. The recording apparatus is provided with: a compressing device for compressing the record information; a first memory for temporarily storing the compressed record information; an optical pickup for writing and reading the compressed record information onto and from the record medium; a control device for controlling the optical pickup to periodically write the compressed record information from the first memory by a predetermined data volume onto the record medium, to stop writing in a record stop duration, and to read the compressed record information from the record medium as compressed reproduction information in the record stop duration; a second memory for storing the compressed reproduction information; and a judgement device for judging whether or not the compressed reproduction information stored in the second memory is coincident with the compressed record information stored in the first memory.
