Information recording method and information recording apparatus

Abstract

To provide a new recording method and recording apparatus with respect to an optical recording medium, the recording method and recording apparatus being able to deal with a high density of an optical recording medium of recent years. Recording of a recording track and a prepit is carried out by sequentially deflecting a single beam.

1 . An information recording method of recording a recording track and a prepit positioned between the tracks characterized by comprising steps of: 
 recording the recording track and the prepit by sequentially deflecting a single beam in a radius direction of the original disc and a tangential direction of the original disc while the original disc goes into a 360-degree roll.    
   
   
       2 . An information recording method of recording a recording track and a prepit positioned between the recording tracks characterized by comprising Steps 1 to 4, which are sequentially repeated while the original disc goes into a 360-degree roll, of: 
 (Step 1) recording the recording track by irradiating a beam onto an original disc;    (Step 2) deflecting the beam used for recording the recording track to a position where a prepit is to be formed when the beam reaches a predetermined position on the original disc;    (Step 3) recording the prepit by irradiating the beam onto the original disc; and    (Step 4) deflecting the beam again to the position of the original disc where the deflection from the recording of the recording track to the recording of the prepit takes place when the beam reaches a predetermined position of the original disc.    
   
   
       3 . An information recording method according to  claim 1 , wherein 
 the beam is an electron beam.    
   
   
       4 . An information recording apparatus including a rotation driving unit for supporting and rotating an original disc, a movement driving unit for moving the rotation driving unit in a radius direction of an original disc, and a beam irradiating means for irradiating a single beam onto the original disc so as to be freely deflectable, the information recording apparatus comprising: 
 a deflection signal generating means for generating a radius direction deflection signal for deflecting the single beam to the radius direction of the original disc and a tangential direction deflection signal for deflecting the single beam to a tangential direction of the original disc; and    a beam deflecting unit for deflecting the single beam on the basis of the radius direction deflection signal and the tangential direction deflection signal to record the track and the prepit on the original disc using the single beam deflected in the radius and tangential directions while the original disc goes into a 360-degree roll.    
   
   
       5 . The information recording apparatus according to  claim 4 , wherein 
 the beam is an electron beam.
