Abstract: A recording device records contents in a plurality of recording media. While the recording device records a content in a recording medium, if a free space of the recording medium runs out, an unrecorded part of the content needs to be recorded in another recording medium. In order to play back all parts of the content, all recording media in which all the parts of the content have been separately recorded are necessary. Particularly, if an internal recording medium included in the recording device has a small space and accordingly a sufficient space is secured by connecting an external removable recording medium to the recording device after the recording has started, parts of the content are separately recorded in the internal recording medium and the external recording medium.

Abstract: The invention relates to a method for preventing interchange of a first optical information carrier (1) with a second optical information carrier in an optical drive. Initially, the light (5) is focused at the first optical information carrier (1) in the optical apparatus followed by the steps of detecting reflected light (8) from the first optical information carrier (1) and generating a plurality of signals (CA, RF, FE) from the detected light (8), such as a focus error signal (FE). Upon obtaining an indication of a signal, e.g. the focus error signal (FE), is absent or reduced below a certain level, there is a step of assessing if the first optical information carrier (1) has been removed from the optical drive. If removed, reproduction of information by the optical drive is made impossible until some pre-determined measures have been taken, e.g. restart of the optical drive or other measures.

Abstract: When a write operation is to be performed for writing digital audio data (track), stored on a hard disk, to a CDR disk in an audio-digital-signal recording apparatus, control is performed, prior to execution of the write operation, such that the digital audio data stored on the hard disk can not be accessed by any other operation than the write operation, to thereby cause the other operation to regard the digital audio data as already erased from the storage section. After completion of the writing or copying of the digital audio data to the disk-shaped storage medium, the digital audio data are actually erased from the hard disk. Thus, even when power failure or shutdown occurs immediately after the copying of the digital audio data and before initiation of the audio data erasure from the hard disk, any operation, other than the write operation, can be prevented from accessing the digital audio data, so that the copyright on the digital audio data can be protected.

Abstract: An information playback apparatus is provided, which can provide a sound which sounds natural by controlling an abrupt change in a tempo in the case of random access playback. When a cue point is registered, audio data which makes seamless playback possible is stored into a cue point memory, and further, the beat density of a playback sound being played when the cue point is registered is measured and stored. When the cue point is specified to start random access playback later, a ratio of the beat density (?×DBPM) of a playback sound being played when the cue point is specified and the beat density (DBPMreg) stored in advance is found. Then, the random access playback is started after the beat density of a playback sound to be played after random access playback is started is corrected to be equal to the beat density when a start of the random access playback is specified.
