Abstract
One embodiment of a tape drive apparatus has a non-volatile memory for storing an identifier. Data that is written by the tape drive apparatus to a loaded tape media is tagged using the identifier. This facilitates to identify the tape drive apparatus that has written the data onto the tape media such as for the purpose of failure analysis. Other devices and methods are included.
Claims17
Tape drive apparatus comprising:
- a non-volatile memory for storing an identifier, the identifier unequivocally identifying the tape drive apparatus within a set of tape drive apparatuses,
- an interface for receiving data,
- a data processing apparatus for tagging the data using the identifier, and
- a data transfer apparatus for writing the tagged data to a loaded tape media, the tape media having groups of tracks, each group of tracks having a predefined number of tracks, the data transfer apparatus being adapted to write the tagged data to tracks of the same group of tracks, such that the identifier is stored multiple times in the same group of tracks.
1 more element
A method of storing data on a tape media, comprising:
- reading an identifier from a non-volatile memory, the identifier being unique to a tape drive apparatus that is used for storing the data on the tape media, tagging the data using the identifier, and
- writing the tagged data to the tape media, the tape media having groups of tracks, each group of tracks having a predefined number of tracks, the tape drive apparatus being adapted to write the tagged data to tracks of the same group of tracks, such that the identifier is stored multiple times in the same group of tracks.
Apparatus for writing data to a storage medium, the apparatus comprising:
- means for storing at least one unique identifier for identification of the apparatus,
- means for labeling the data using the unique identifier, and
- means for writing the labeled data to the storage medium, the storage medium having groups of tracks, each group of tracks having a predefined number of tracks, the means for writing being adapted to write the labeled data to tracks of the same group of tracks, such that the unique identifier is stored multiple times in the same group of tracks.
