[0040] used to describe related technologies figure 1 The structure of is basically applicable to the structure of the recording apparatus according to the first embodiment of the present invention. However, the function of each structural device of this embodiment is completely different from the previous examples. First, refer to figure 2 The processing procedure of the controller 2 during the recording operation will be described.
[0041] When music data is input from the music data output device 1 in step S1, it proceeds to step S2 of starting recording. In step S2, recording processing (encoding and encryption) is performed for each input data of a specific size, and in step S3, the encrypted music data is stored into the buffer of the memory 3. It is then monitored in step S4 to check whether there is still available capacity in the buffer. When it is judged that there is no remaining capacity in the buffer (YES in step S4), a request to write the music data of the...

[0052] Like the first embodiment, figure 1 The structure of is applicable to the structure of the recording apparatus according to the second embodiment of the present invention. Controller 2 processes with figure 2 is the same as that of the first embodiment shown, and therefore its description will be omitted.
[0053] will be passed by reference Figure 5 The shown flow chart explains the processing procedure of the system controller (recorder) 4 according to the present embodiment at the time of recording action. When recording starts, the system controller 4 enters a recording loop in step S31, and reaches a state of waiting for a write request from the controller 2 in step S32. When there is no writing request from the controller 2 (no in step S32), proceed to step S33, and judge whether to start a file for recording the music data of the next segment in the recording medium 6. If it is not started, then enter step S34, and execute the file start processing for the ...

[0061] Figure 7 is a block diagram showing the configuration of a recording apparatus according to a third embodiment of the present invention. exist Figure 7 In , reference numeral 7 is a protected portion for requesting a file operation for changing a piece of music. When there is a write request from the controller 2 to the system controller 4, if the delay time of writing the music data into the recording medium 6 exceeds a certain time, the protection section 7 performs protection on a request to change a file operation of a piece of music ( pending) processing. Also, the file end processing of the data in the recording medium 6 storing the previous music data is not executed and delayed.
[0062] In the recording apparatus of this embodiment, the processing of the controller 2 is the same as figure 2 It is the same as that of the first embodiment shown, and its description is omitted.
[0063] will be passed by reference Figure 8 The shown flow chart explains t...
