Apparatus, method and computer program product for reading information stored in storage medium
First Claim
1. An apparatus for reproducing information, comprising:
- a memory unit which stores charge;
a reading unit which obtains an amount of the charge stored in the memory unit, and reads information by determining a value based on a comparison of the amount of the charge with a first threshold;
an error detection unit which determines whether the information read has an error; and
a threshold generation unit which generates a second threshold having a value different from that of the first threshold used in reading the information, when the error detection unit determines that the information has an error,wherein the reading unit further reads the information by determining a value based on a comparison of the amount of the charge with the second threshold after the error detection unit determines that the information has the error.

Abstract
An apparatus for reproducing information includes a memory unit which stores charge; a reading unit which obtains an amount of the charge stored in the memory unit, and reads information by determining a value based on a comparison of the amount of the charge with a first threshold; an error detection unit which determines whether the information read has an error; and a threshold generation unit which generates a second threshold having a value different from that of the first threshold used in reading the information, when the error detection unit determines that the information has an error, wherein the reading unit further reads the information by determining a value based on a comparison of the amount of the charge with the second threshold after the error detection unit determines that the information has the error.

12. A method for reproducing information comprising:
-
obtaining an amount of the charge stored in a memory unit which stores charge; reading information by determining a value based on a comparison of the amount of the charge with a first threshold; determining whether the information read has an error; generating a second threshold different from the first threshold used in reading the information when it is determined that the information has the error; and reading the information by determining a value based on a comparison of the amount of the charge with the second threshold after it is determined that the information has the error.

13. A computer program product having a computer readable medium including programmed instructions for reproducing information in a storage medium, wherein the instructions, when executed by a computer, cause the computer to perform:
-
obtaining an amount of the charge stored in a memory unit which stores charge; reading information by determining a value based on a comparison of the amount of the charge with a first threshold; determining whether the information read has an error; generating a second threshold different from the first threshold used in reading the information when it is determined that the information has the error; and reading the information by determining a value based on a comparison of the amount of the charge with the second threshold after it is determined that the information has the error.
