11 is a flowchart of a radio recording method according to another embodiment. The order of S10 to S100 shown in Fig. 10 may be changed.

In one embodiment, the radio recording method may further comprise a forward step S100.

In one embodiment, the fast forward step S100 moves the playback time forward for a predetermined time when the fast forward instruction is issued while the playback point is moved backward, and the digital data is played back from the point forward. In the forward winding step S100, it is possible to perform the forward winding command without distinguishing whether the encoded digital data is music data or non-music data. The predetermined time may be, for example, several seconds to several tens of seconds.

In one embodiment, the fast forward step S100 is a step in which if the fast forward command is issued while the playback point is moved backward, Playback. The present invention is not limited to this. In the forward winding step S100, the digital data may be reproduced from the point in time that is advanced by at least twice the time until a reproduction command is issued after the forward command is issued.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation and that those skilled in the art will recognize that various modifications and equivalent arrangements may be made therein. It will be possible. Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
