Method for successively recording data in hybrid digital recorder
First Claim
1. A method for successively recording data in a hybrid digital recorder, comprising:
- a) recording an input data stream on a detachable recording medium;
b) temporarily storing the input data stream in a predetermined memory when the recording medium has no redundant area in which the data stream can additionally be recorded;
c) if the recording medium is replaced with a new recording medium, while temporarily storing the input data stream in the predetermined memory reading the data stream temporarily stored in the memory, and recording the read data stream on the new recording medium; and
d) recording a data stream input afterward on the new recording medium, if the data stream temporarily stored in the memory is read and recorded on the new recording medium.

Abstract
A method for successively recording data in a hybrid digital recorder. If an optical disc has no redundant area when a hybrid digital recorder in which an optical disc recorder and an HDD recorder, etc. are integrated in one body records an input data stream on the optical disc, the input data stream is temporarily stored in an HDD. If the optical disc is replaced with a new optical disc, the input data stream is temporarily stored in the HDD, and at the same time the data stream having been temporarily stored in the HDD is read and recorded on the new optical disc at a high speed. If all the data streams temporarily stored in the HDD are read and recorded on the new optical disc, the following data stream is recorded on the new optical disc. Therefore, an external input data stream such as a long-term broadcast program is distributed to a plurality of optical discs, and is stored on the optical discs without generating any lost data.

14. A hybrid digital recorder apparatus for successively recording data therein, comprising:
-
a drive for recording an input data stream on a detachable recording medium;
a memory for storing the input data stream; and
a controller for controlling the drive and the memory such that it temporarily stores the input data stream in the memory when the recording medium has no redundant area in which the data stream can additionally be recorded, if the recording medium is replaced with a new recording medium, while temporarily storing the input data stream in the memory, reads the data stream temporarily stored in the memory and records the read data stream on the new recording medium, and records a data stream input afterward on the new recording medium if the data stream temporarily stored in the memory is read and recorded on the new recording medium. - View Dependent Claims (15, 16, 17, 18, 19, 20)
