Duplicator for recording medium and method for duplicating recording medium

Abstract

The present invention relates to a duplicator for recording medium and a method for duplicating recording medium, wherein a fast duplicating effect is achieved by FIFO buffers and direct memory access controllers (DMACs).

1 . A duplicator for recording medium, comprising: 
 a source recording medium;    a source DMAC;    a source FIFO buffer;    a multiplexer;    a plurality of target FIFO buffers;    a plurality of target DMACs; and    a plurality of target recording mediums,    wherein the data of said source recording medium are transmitted to said source FIFO buffer through said source DMAC; the data of said source FIFO buffer are transmitted to a plurality of said target FIFO buffers through said multiplexer; and the data of said target FIFO buffer are transmitted to said target recording medium through said target DMAC.    
     
     
         2 . (Cancelled)  
     
     
         3 . The duplicator for recording medium as defined in  claim 1 , further comprising a plurality of comparators, wherein the data of said source recording medium are transmitted to said source FIFO buffer through said source DMAC; the data of said target recording medium are transmitted to said target FIFO buffer through said target DMAC; and the data of said source FIFO buffer are transmitted to said comparators through said multiplexer and compared with the data of target FIFO buffer by said comparators.  
     
     
         4 . (Cancelled)  
     
     
         5 . The duplicator for recording medium as defined in  claim 1 , wherein said recording medium is a hard disc.  
     
     
         6 . The duplicator for recording medium as defined in  claim 1 , wherein said recording medium is an optical disc.  
     
     
         7 . The duplicator for recording medium as defined in  claim 1 , wherein said recording medium is a rewritable optical disc.  
     
     
         8 . The duplicator for recording medium as defined in  claim 1 , wherein said recording medium is a floppy disc.  
     
     
         9 . The duplicator for recording medium as defined in  claim 1 , wherein said recording medium is a memory.  
     
     
         10 . The duplicator for recording medium as defined in  claim 1  or  3 , further comprising a transferring interface provided between said source recording medium and said source DMAC.  
     
     
         11 . The duplicator for recording medium as defined in  claim 10 , wherein said transferring interface is an ATA, serial ATA or SCSI control interface.  
     
     
         12 . (Cancelled)  
     
     
         13 . (Cancelled)
