Abstract
A data demodulating device which converts an RLL code string obtained by converting a data string in which information bits including a special bit having a value representing the content of a signal process at the time of demodulating data within a target section included in an input signal are inserted with a constant interval in accordance with a modulation table having a variable length conversion rule, in accordance with a demodulation table corresponding to the modulation table, includes: a shaping unit configured to subject to two or more signal processes; and a selecting unit configured to select the content of the signal process by the shaping unit based on the information bits.
Claims10
A data demodulating device which converts an RLL code string obtained by converting a data string in which information bits including a special bit having a value representing the content of a signal process at the time of demodulating data within a target section included in an input signal are inserted with a constant interval in accordance with a modulation table having a variable length conversion rule, in accordance with a demodulation table corresponding to said modulation table,
- said data demodulating device comprising:
- a shaping unit configured to subject to two or more signal processes;
- and
- a selecting unit configured to select the content of said signal process by said shaping unit based on said information bits.
A data demodulating method of a data demodulating device including a shaping unit which subjects to two or more signal processes which convert an RLL code string obtained by converting a data string in which information bits including a special bit having a value representing the content of a signal process at the time of demodulating data within a target section included in an input signal are inserted with a constant interval in accordance with a modulation table having a variable length conversion rule, in accordance with a demodulation table corresponding to said modulation table,
- said method comprising:
- selecting the content of said signal process by said shaping unit based on said information bits.
A program causing a computer to execute processing of a data demodulating device including a shaping unit which subjects to two or more signal processes which convert an RLL code string obtained by converting a data string in which information bits including a special bit having a value representing the content of a signal process at the time of demodulating data within a target section included in an input signal are inserted with a constant interval in accordance with a modulation table having a variable length conversion rule, in accordance with a demodulation table corresponding to said modulation table,
- said processing comprising:
- selecting the content of said signal process by said shaping unit based on said information bits.
