Disk recording and reproducing device

Abstract

Abstract PURPOSE:To attain dubbing operation by only by one disk by arranging a recording head prior to a reproducing head and sending a signal outputted from the reproducing head to the recording head. CONSTITUTION:A servo circuit A14 is driven by an output from an address reading circuit A13 so that a laser beam 4a is projected on the head of a reproducing pat 101 and the beam 4a is waited in a still state. A servo circuit B17 is driven by an output from an address reading circuit B16 so that a laser beam 6a is projected after the end part of a reproducing pat 102 and the beam 6a is projected after the end part of a reproducing part 102 and the beam 6a is waited in a still state based upon a slight output. When both the beams 4a, 6a are held at the waited state, heads 4, 6 execute recording operation and information in the reproducing part 101 is successively recorded in a recording part 103. In case an operation stop signal is not generated from a control circuit 18 when the head 4 ends the reproducing of the reproducing part 102, dubbing operation is continued and information after the recording part 103 is successively sent to the head 6 so that information in the reproducing parts 101, 102 is repeatedly recorded in the part following the recording part 104.
