Information recording device and method, and information recording system

An information recording method comprising steps of:

• extracting a predetermined standard-defined UMID buried in material signals to be recorded to a replaceable recording medium;
• and
• writing/reading information to/from a contactless information storage means appended to or incorporated in the replaceable recording medium and which is operative responsively to an electromagnetic field to send or receive information in a contactless manner to or from outside via the electromagnetic field, the extracted UMID being written to the contactless information storage means,
• wherein data is prevented from being written over an existing record and data is prevented from being erroneously erased by collating end of source point information recorded in the contactless information storage means with end of source point information recorded on the replaceable recording medium thereby locating an end of source point.

An information recorder comprising:

• means for generating, from information other than material signals to be recorded to a replaceable recording medium, a UMID indicating the material signals;
• and
• means for writing/reading information to/from a contactless information storage means appended to or incorporated in the replaceable recording medium and which is operative responsively to an electromagnetic field to send or receive information in a contactless manner to or from outside via the electromagnetic field, the writing/reading means writing the generated UMID to the contactless information storage means,
• wherein data is prevented from being written over an existing record and data is prevented from being erroneously erased by collating end of source point information recorded in the contactless information storage means with end of source point information recorded on the replaceable recording medium thereby locating an end of source point.

An information recording system comprising:

• means for writing/reading information to/from a contactless information storage means appended to or incorporated in the replaceable recording medium and which is operative responsively to an electromagnetic field to send or receive information in a contactless manner to or from outside via the electromagnetic field;
• an information recorder for writing, to the contactless information storage means by the writing/reading means, a UMID extracted from material signals to be recorded and indicating the material signals recorded to the recording medium or a UMID generated from information other than the material signals to be recorded to the recording medium and indicating the material signals;
• and
• a UMID storage unit for storing a UMID read from the contactless information storage means appended to or incorporated in each of a plurality of recording mediums,
• wherein data is prevented from being written over an existing record and data is prevented from being erroneously erased by collating end of source point information recorded in the contactless information storage means with end of source point information recorded on the replaceable recording medium thereby locating an end of source point.

An information recording method comprising steps of:

• writing a UMID extracted from material signals to be recorded and indicating the material signals or a UMID generated from information other than the material signals to be recorded to the recording medium and indicating the material signals to a contactless information storage means appended to or incorporated in the replaceable recording medium and which is operative responsively to an electromagnetic field to send or receive information in a contactless manner to or from outside via the electromagnetic field;
• and
• storing the UMID read from the contactless information storage means appended to or incorporated in each of a plurality of recording mediums,
• wherein data is prevented from being written over an existing record and data is prevented from being erroneously erased by collating end of source point information recorded in the contactless information storage means with end of source point information recorded on the replaceable recording medium thereby locating an end of source point.
