Abstract
A recording device includes: a recording unit that records plural objects including data and metadata related to the data on a portable recording medium, and executes a process of recording first set data, which is a set of the metadata included in the object, at every predetermined timing after recording at least one of the objects, wherein each piece of the first set data is a set of the metadata included in the object recorded after recording of immediately preceding recorded first set data.
Claims14
A recording device comprising:
- a recording unit that records a plurality of objects including data and metadata related to the data on a portable recording medium, and executes a process of recording first set data, which is a set of the metadata included in the object, at every predetermined timing after recording at least one of the objects,
- wherein each piece of the first set data is a set of the metadata included in the object recorded after recording of immediately preceding recorded first set data.
A readout device comprising:
- a specifying unit that specifies a position on a portable recording medium of an object recorded in a data partition of the portable recording medium including a reference partition and the data partition in which an object including data and metadata related to the data is recorded, by using at least one of second set data recorded in the reference partition, the second set data recorded in the data partition, first set data recorded in the data partition, or the metadata recorded in the data partition;
- and
- a readout unit that reads the object recorded at the position specified by the specifying unit.
A recording method executed by a computer, the method comprising:
- recording a plurality of objects including data and metadata related to the data on a portable recording medium;
- and
- executing a process of recording first set data, which is a set of the metadata included in the object, at every predetermined timing after recording at least one of the objects, each piece of the first set data being a set of the metadata included in the object recorded after recording of immediately preceding recorded first set data.
A non-transitory storage medium storing a program for causing a computer to execute a recording processing, the recording processing comprising:
- recording a plurality of objects including data and metadata related to the data on a portable recording medium;
- and
- executing a process of recording first set data, which is a set of the metadata included in the object, at every predetermined timing after recording at least one of the objects,
- wherein each piece of the first set data is a set of the metadata included in the object recorded after recording of immediately preceding recorded first set data.
A readout method executed by a computer, the method comprising:
- specifying a position on a portable recording medium of an object recorded in a data partition of the portable recording medium including a reference partition and the data partition in which the object including data and metadata related to the data is recorded, by using at least one of second set data recorded in the reference partition, the second set data recorded in the data partition, first set data recorded in the data partition, or the metadata recorded in the data partition;
- and
- reading the object recorded at the specified position.
A non-transitory storage medium storing a program for causing a computer to execute a readout processing, the readout processing comprising:
- specifying a position on a portable recording medium of an object recorded in a data partition of the portable recording medium including a reference partition and the data partition in which the object including data and metadata related to the data is recorded by using at least one of second set data recorded in the reference partition, the second set data recorded in the data partition, first set data recorded in the data partition, or the metadata recorded in the data partition;
- and
- reading the object recorded at the specified position.
A magnetic tape on which a plurality of objects including data and metadata related to the data are recorded, and a process of recording first set data, which is a set of the metadata included in the object, is executed at every predetermined timing after at least one of the objects is recorded,
- wherein each piece of the first set data is a set of the metadata included in the object recorded after recording of immediately preceding recorded first set data.
