  • Patent number: 7751690
    Abstract: A recording and reproducing apparatus for reproducing information recorded on a recording medium concurrently while recording the information, includes a compression section, a temporary storage section, a reproducing process section, and a storage section. The compression section reads the information recorded on the recording medium and compresses read information. The temporary storage section stores compressed information provided by the compression process. The reproducing process section decompresses the compressed information output thereto from the temporary storage section and reproduces decompressed information. The storage section stores the compressed information output thereto from the temporary storage section.

  • Patent number: 7525885
    Abstract: An information reproduction and recording apparatus able to prevent invalid data not required for recording from being recorded on a recording medium when transferring reproduced information by a small number of signal lines such as a three-line serial peripheral interface, wherein a music data reproducing unit outputs a data signal DATA and clock signals LRCK and BCK to a valid recording period control unit and outputs a SPACE signal to the valid recording period control unit while outputting music data containing track interval data, the signals are transferred to a high speed encoder and the data signal DATA is encoded and recorded on a hard disk by an HDD based on the clock signals LRCK and BCK while the SPACE signal is being output, and the valid recording period control unit suspends transfer of the clock signal LRCK and prevents recording of invalid data on the hard disk while the SPACE signal is not being output.

  • Publication number: 20050259972
    Abstract: A recording and reproducing apparatus for reproducing information recorded on a recording medium concurrently while recording the information, includes a compression section, a temporary storage section, a reproducing process section, and a storage section. The compression section reads the information recorded on the recording medium and compresses read information. The temporary storage section stores compressed information provided by the compression process. The reproducing process section decompresses the compressed information output thereto from the temporary storage section and reproduces decompressed information. The storage section stores the compressed information output thereto from the temporary storage section.
