Recording method, recording apparatus, reproducing method and reproducing apparatus

In a recording apparatus for recording data on a predetermined medium, the recording apparatus comprising:

• means for discriminating a type of a medium in which data are recorded;
• means for detecting an address at which data are recorded;
• means for replacing data at a section in which decoding information is to be located with predetermined information when said address detection means detects an address of specific position at which said decoding information is located after said discrimination means discriminated a specific type of medium in which data are recorded;
• and
• means for recording the data replaced by said replacement means in said medium.

A reproducing method comprising the steps of:

• reproducing data from a medium;
• discriminating a type of a medium reproduced at said reproduction step;
• detecting an address at which data reproduced at said reproduction step are recorded;
• and
• replacing reproduction data in a section in which decoding information is to be located with predetermined information when said address detection step detects an address of specific position at which said decoding information is located after said discrimination step discriminated data reproduced from a specific type of medium.

A reproducing apparatus comprising:

• means for reproducing data from a medium;
• means for discriminating a type of a medium from which data are reproduced by said reproduction means;
• means for detecting an address at which data reproduced by said reproduction means are recorded;
• and
• replacement means for replacing reproduction data at a section in which decoding information is to be located with predetermined information when said address detection means detects an address of specific position at which said decoding information is located after said discrimination means discriminated data reproduced from a specific type of medium.

A recording method comprising the steps of:

• replacing data at a section in which decoding information is to be recorded with predetermined information when said address detection step detects an address of specific position at which said decoding information is located;
• and
• recording data replaced at said replacement step in said medium.

A reproducing method comprising the steps of:

• reproducing data from a medium;
• detecting an address at which data reproduced at said reproduction step are recorded;
• and
• replacing reproduction data at a section in which decoding information is to be located with predetermined information when said address detection step detects an address of specific position at which said decoding information is located.
