Abstract
In recording information, meta data defined in SMPTE 298M and 335M, buried in video and audio material signals to be recorded to a magnetic tape (30) are extracted, the thus extracted meta data or meta data generated from information other than the material signals, are written to a contactless memory tag (37), whereby it is made possible to acquire meta data about material signals recorded in a recording medium without actual reading of the material signals in the recording medium and use the meta data for search, validation, etc.
Claims12
An information recorder comprising:
- means for extracting predetermined standard-defined meta data buried in material signals to be recorded to a replaceable recording medium;
- 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 meta data extracted by the extracting means to the contactless information storage means.

An information recording method comprising steps of:
- extracting predetermined standard-defined meta data 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 meta data being written to the contactless information storage means.
1 more element
An information recorder comprising:
- means for generating, from material signals to be recorded to a replaceable recording medium, meta data associated with 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 meta data to the contactless information storage means.

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 means of the writing/reading means, predetermined standard-defined meta data extracted from material signals to be recorded to the recording medium or meta data generated from information other than the material signals written to the recording medium;
- and
- a meta data storage unit for storing the meta data read from the contactless information storage means appended to or incorporated in each of a plurality of recording mediums.
