Abstract

A Copying Apparatus for copying a recoding medium, a method thereof and a computer program thereof is provided, wherein the recording medium is copy-protected by a predetermined method.

1 . A recording medium copying apparatus for copying a recording medium which comprises an overlap zone where addresses overlap, comprising: 
 a file reading unit for reading and managing a file in a forward and/or reverse direction, said file recorded on an original recording medium to be copied;    a file comparing and identifying unit for comparing said files read from said original recording medium and identifying whether said files are identical to each other or not;    an address processing unit for collecting addresses of said files with regard to said original recording medium and generating and assigning an address at which said file is recorded on a duplicate recording medium; and    a file recording unit for recording said file on said duplicate recording medium at said address assigned by said address processing unit in order that an address structure of said duplicate recording medium can be the same as that of said original recording medium.    
   
   
       2 . A recording medium copying apparatus as claimed in  claim 1 , wherein said file reading unit reads said original recording medium in a forward direction which is from a head of said original recording medium at which an address is smallest to an end of said original recording medium at which an address is largest and retrieves said file recorded on said original recording medium, and 
 uniquely identifies said file read in said forward direction according to an address thereof and/or an retrieved order and stores and manages said file in a memory.    
   
   
       3 . A recording medium copying apparatus as claimed in  claim 2 , wherein said file reading unit reads said original recording medium in a reverse direction which is from said end to said head of said original recording medium and retrieves said file recorded on said original recording medium, and 
 uniquely identifies said file read in said reverse direction according to an address thereof and/or an order opposite to said retrieved order and stores and manages said file in a memory.    
   
   
       4 . A recording medium copying apparatus as claimed in  claim 3 , wherein said file reading unit comprises: 
 a forward direction file reading unit for reading said original recording medium in said forward direction, retrieving said file recorded on said original recording medium, uniquely identifying said file read in said forward direction according to said address thereof and/or said retrieved order and storing and managing said file in said memory; and    a reverse direction file reading unit for reading said original recording medium in said reverse direction, retrieving said file recorded on said original recording medium, uniquely identifying said file read in said reverse direction according to said address thereof and/or said order opposite to said retrieved order and storing and managing said file in said memory.    
   
   
       5 . A recording medium copying apparatus as claimed in  claim 1 , wherein said file reading unit reads said original recording medium in said forward and reverse directions in parallel.  
   
   
       6 . A recording medium copying apparatus as claimed in  claim 1 , wherein said address processing unit assigns said address at which said file read from said original recording medium is recorded on said duplicate recording medium in order that said address structure of said duplicate recording medium is the same as that of said original recording medium.  
   
   
       7 . A recording medium copying apparatus as claimed in  claim 6 , wherein said address processing unit assigns said address with regard to said duplicate recording medium in order that a forward direction file and a reverse direction file which are judged not to be identical to each other by said file comparing and identifying unit have the same address, said forward and reverse direction files corresponding to each other.  
   
   
       8 . A recording medium copying apparatus as claimed in  claim 1 , wherein said file recording unit records either said forward or reverse direction file judged to be identical to each other on said duplicate recording medium, 
 while recording said forward direction file judged not to be identical on said duplicate recording medium in advance and then recording said reverse direction file judged not to be identical at an corresponding address of said duplicate recording medium.    
   
   
       9 . A recording medium copying apparatus as claimed in  claim 1 , wherein a set of data divided in a predetermined unit per which a process is performed is taken as said file.  
   
   
       10 . A recording medium copying method for copying a recording medium which comprises an overlap zone where addresses overlap, comprising the steps of: 
 reading an original recording medium in a forward or reverse direction and retrieving a file;    allowing said file read in said forward direction to be identified in a retrieved order;    allowing said file read in said reverse direction to be identified in an order opposite to said retrieved order; and    recording said file read in said forward or reverse direction on a duplicate recording medium in order that an address structure of said duplicate recording medium can be the same as that of said original recording medium.    
   
   
       11 . A recording medium copying method as claimed in  claim 10  further comprising a step of storing an address of said file with regard to said original recording medium to correspond to said file read from said original recording medium.  
   
   
       12 . A recording medium copying method as claimed in  claim 10 , wherein said file read in said forward direction is assigned with an identification number sequentially increasing according to an order in which said file is retrieved.  
   
   
       13 . A recording medium copying method as claimed in  claim 10 , wherein said file read in said reverse direction is assigned with an identification number sequentially decreasing according to an order in which said file is retrieved.  
   
   
       14 . A recording medium copying method as claimed in  claim 10 , wherein said original recording medium is read in said forward and reverse directions in parallel in said step of reading.  
   
   
       15 . A recording medium copying method as claimed in  claim 10 , wherein a set of data divided in a predetermined unit per which a process is performed is taken as said file.  
   
   
       16 . A computer program for copying a recording medium which comprises an overlap zone where addresses overlap, comprising: 
 a file reading module for reading and managing a file in a forward and/or reverse direction, said file recorded on an original recording medium to be copied;    a file comparing and identifying module for comparing said files read from said original recording medium and identifying whether said files are identical to each other or not;    an address processing module for collecting addresses of said files with regard to said original recording medium and generating and assigning an address at which said file is recorded on a duplicate recording medium; and    a file recording module for recording said file on said duplicate recording medium at said address assigned by said address processing module in order that an address structure of said duplicate recording medium can be the same as that of said original recording medium.    
   
   
       17 . A computer program as claimed in  claim 16 , wherein said address processing module stores an address of said file with regard to said original recording medium to correspond to said file read from said original recording medium.  
   
   
       18 . A computer program as claimed in  claim 16 , wherein said file read in said forward direction is assigned with an identification number sequentially increasing according to an order in which said file is retrieved.  
   
   
       19 . A computer program as claimed in  claim 16 , wherein said file read in said reverse direction is assigned with an identification number sequentially decreasing according to an order in which said file is retrieved.  
   
   
       20 . A computer program as claimed in  claim 16 , wherein said original recording medium is read in said forward and reverse directions in parallel.  
   
   
       21 . A computer program as claimed in  claim 16 , wherein a set of data divided in a predetermined unit per which a process is performed is taken as said file.
