Patent ID: 7880946

Claim:
A method of improving quality of a signal reproduced from a holographic storage medium in which a hologram is recorded by interference between a signal beam and a reference beam, the method comprising: determining a page crosstalk value caused by an adjacent page to a page to be reproduced from the holographic storage medium on the basis of on-pixel crosstalk values caused by a plurality of on-pixels of the adjacent page; removing the determined page crosstalk value from a reproduced signal of the page to be reproduced; in response to the adjacent page being a page that is initially reproduced, determining a page crosstalk value caused by the page to be reproduced on the basis of on-pixel crosstalk values caused by a plurality of on-pixels included in the page to be reproduced; removing the page crosstalk value caused by the page to be reproduced from a reproduced signal of the adjacent page; and further removing a page crosstalk value from the page to be reproduced using the adjacent page from which the page crosstalk value caused by the page to be reproduced has been removed.
