Abstract:
1. A digital recording and/or reproducing apparatus comprising: a reproducing unit for reading out digital data from a first disk-shaped optical disk recording medium having a known read out rate at a first transmission rate substantially higher than said known read out rate of said first disk shaped optical disk recording medium; a temporary storage unit directly connected to said reproducing unit and including a hard disk drive for temporarily storing digital data read out by said reproducing unit, wherein said temporary storage unit includes an input/output calculation unit for processing the digital data read out from the reproducing unit with modulation, error correction, and encoding before feeding to said hard disk drive of the temporary storage unit for temporarily storing the digital data; a recording unit for recording digital data read out from said storage unit in a second disk-shaped optical disk recording medium having a known recording rate equal to the known readout rate of said first disk-shaped optical disk; and controlling means for controlling respective operations of said reproducing unit, said temporary storage unit and said recording unit, said controlling means controlling said input/output calculation unit to cause the digital data from said reproducing unit to be written in said hard disk drive of said temporary storage unit at a second transmission rate higher than the known recording rate of said second disk-shaped optical disk recording medium and lower than said first transmission rate, said controlling means controlling said input/output calculation unit to cause the digital data to be read out from said hard disk drive of said temporary storage unit at said second transmission rate, and for outputting the read out data to said recording unit at said known recording rate of said second disk-shaped optical disk and causing the routed read out data to be recorded in said second disk-shaped optical disk recording medium.
