1. A recording method, comprising the steps of:
- when content data to which additional data has been added is recorded, detecting whether or not the additional data has been detected from the content data to be recorded;
when the additional data has been detected, recording the content data with the original quality; and
when the additional data has not been detected, recording the content data with a lower quality than the original quality to the record medium,wherein the additional data contains copyright data for controlling recording operation,wherein the recording step of lower quality is performed by converting low order bits of the data to all zeros and recording the resultant data to the record medium.

Abstract
A reproducing method is disclosed, that comprises the steps of determining whether or not additional data has been read from data that had been read from a loaded record medium, and when the determined result represents that the additional data has been read from the data, performing a reproducing process for the data that had been read from the record medium corresponding to reward data contained in the additional data.

8. A recording apparatus for a record medium, comprising:
-
additional data detecting portion for detecting additional data added to input content data; a selecting circuit portion for selecting the quality of the input content data; an encoder for performing an encoding process for causing output content data of the selecting circuit to be recorded; a head portion to which output data of the encoder is supplied; and a controlling portion to which a detected output of the additional data detecting portion is supplied, when the additional data has been detected by the additional data detecting portion, the controlling portion causing the selecting circuit portion to output content data with the same quality as the input data, and wherein when the additional data detecting portion has not detected the additional data, the controlling portion causes the selecting circuit portion to output content data with a lower quality than the input data, wherein the selecting circuit portion has; a buffer memory for buffering the input data; a selector for selecting low order bit data of the output data of the buffer memory or zero data corresponding to a control signal that is output from the controlling portion and outputting the selected data; and a combining portion for combining high order bit data of the output data of the buffer memory and the output data of the selector. - View Dependent Claims (9, 10, 11, 12)
