Abstract

An information recording device according to the present invention includes an HDD 5, a DVD 6 and a VCR 7. During transferring and recording information from DVD 6 onto VCR 7, a transfer control circuit 20 short-circuits between an input node and an output node. Accordingly, an image signal line L1 or L2 is electrically connected to an image signal line L3 through a switch SW and transfer control circuit 20. Namely, information is transmitted to the VCR without providing a direct information transmission path from DVD 6 to VCR 7. The configuration according to the present invention enables bidirectionally transferring information among HDD 5, DVD 6 and VCR 7 with a single switch, thereby enabling dubbing with a simple configuration.

Claims

1. An information recording device comprising:

a first recording unit capable of recording information onto a first recording medium;

a second recording unit capable of recording information onto a second recording medium;

a third recording unit capable of recording information onto a third recording medium, wherein each of the recording units comprises;

a transfer control circuit for controlling a transfer of information from and to the other recording units; and

an information recording circuit for recording information transmitted thereto during transferring;

a first transfer line connecting an output node of the transfer control circuit of said first recording unit to input nodes of the transfer control circuits of said second and third recording units to transfer information therebetween;

a second transfer line connecting an output node of the transfer control circuit of said second recording unit to an input node of the transfer control circuit of said first recording unit to transfer information therebetween; and

a third transfer line connecting an output node of the transfer control circuit of said third recording unit to the input node of the transfer control circuit of said first recording unit to transfer information therebetween,

wherein said first recording unit comprises a switch to switch the connection of the input node of the transfer control circuit of said first recording unit to the second and third transfer lines in response to an instruction,

wherein the transfer control circuit of said first recording unit comprises a short-circuit control circuit to short-circuit between the input node and the output node during transferring from one of said second recording unit and said third recording unit to the other one of them,

wherein said switch electrically connects said second transfer line to said input node during transferring from said second recording unit to said third recording unit and electrically connects said third transfer line to said input node during transferring from said third recording unit to said second recording unit, and

wherein said first recording unit corresponds to a hard disc recorder, said second recording unit corresponds to a DVD recorder, and said third recording unit corresponds to a video cassette recorder.

2. An information recording device comprising:

a first recording unit capable of recording information onto a first recording medium;

a second recording unit capable of recording information onto a second recording medium;

a third recording unit capable of recording information onto a third recording medium, wherein each of the recording units comprises;

a transfer control circuit for controlling the transfer of information from and to the other recording units; and

an information recording circuit for recording information transmitted thereto during transferring;

a first transfer line connecting an output node of the transfer control circuit of said first recording unit to input nodes of the transfer control circuits of said second and third recording units to transfer information therebetween;

a second transfer line connecting an output node of the transfer control circuit of said second recording unit to an input node of the transfer control circuit of said first recording unit to transfer information therebetween; and

a third transfer line connecting an output node of the transfer control circuit of said third recording unit to the input node of the transfer control circuit of said first recording unit to transfer information therebetween,

wherein said first recording unit comprises a switch to switch the connection of the input node of the transfer control circuit of said first recording unit to the second and third transfer lines in response to an instruction, and

wherein the transfer control circuit of said first recording unit comprises a short-circuit control circuit to short-circuit between the input node and the output node during transferring from one of said second recording unit and said third recording unit to the other one of them.

3. The information recording device according to claim 2, wherein said switch electrically connects said second transfer line to said input node during transferring from said second recording unit to said third recording unit and electrically connects said third transfer line to said input node during transferring from said third recording unit to said second recording unit.
