A recording system includes an information receiver having a function of decoding
a general-purpose data-description language, and a recorder having a data recording
region for recording data from the information receiver and a document-type-definition
recording region for recording at least document-type-definition information on
the general-purpose data-description language. When being linked to the information
receiver, the recorder transmits the recorded document-type-definition information
to the information receiver, and the information receiver transmits, based on the
received document-type-definition information, predetermined data to the recorder.
