Abstract:
A dubbing system for dubbing at least one of programs from a first recording medium in a reproducing unit to a second recording medium in a recording unit, comprising:operating means for selecting one of high-speed dubbing and normal-speed dubbing that is to be performed on a predetermined program recorded on said first recording medium; clocking means for executing a clocking operation; clock control means for starting said clocking operation by said clocking means when said predetermined program is high-speed dubbed from said first recording medium to said second recording medium; storage means for storing clock information of said clocking means in correspondence to each program recorded on said first recording medium; power supply means for supplying a power at least to said storage means; detecting means for detecting whether the power from said power supply means to said storage means has been interrupted; and control means for controlling, when selecting by said operating means high-speed dubbing of said predetermined program recorded on said first recording means to said second recording means, permission or inhibition of the high-speed dubbing with reference to said clock information stored in said storage means corresponding to said predetermined program recorded on said first recording means, and, when an interruption of the power supply from said power supply means to said storage means is detected by said detecting means and then the power supply to said storage means is restarted, inhibiting the high-speed dubbing of all programs recorded on said first recording means until a predetermined duration of time passes.
