Patent ID: 7167428

Claim:
An optical record carrier recording apparatus for recording data by irradiating a radiation beam ( 5 ) onto a recording surface ( 2 ) of an optical record carrier ( 1 ) comprising: a radiation source ( 4 ) for providing the radiation beam ( 5 ), a phase locked loop ( 10 ) for providing a clock signal (clk), a recording signal generation unit ( 9 ) for generating a recording signal (S 1 ) from a received information signal (S) using said clock signal (clk), a device ( 8 ) for generating a timing signal (S 2 ) from said recording signal (S 1 ), said timing signal (S 2 ) having an increased timing resolution with respect to said recording signal (S 1 ), and a driver unit ( 7 ) for receiving said timing signal (S 2 ) and driving said radiation source ( 4 ), wherein said device ( 8 ) for generating said recording signal (S 1 ) comprises: delay means ( 11 ) for receiving said recording signal (S 1 ) and for generating said timing signal (S 2 ), said delay means comprising a first group ( 14 ) of delay cells ( 20 ) having a first delay and a second group ( 17 ) of delay cells ( 22 ) having a second delay, the difference between said first and said second delay forming a unit delay being smaller than said first and said second delay, and selection means ( 12 ) for selecting the number of unit delays for delaying the recording signal (S 1 ) by controlling the number of delay cells ( 20 , 22 ) of said first and said second group ( 14 , 17 ) to be passed by said recording signal (S 1 ).
