摘要:
A tape drive system for a tape cartridge including a tape and wireless identification tag may read information from the wireless identification tag and write the information to the tape. The tape drive system may toggle a bit stored on the wireless identification tag to indicate that the information has been written to the tape. The information may include tape initialization information.

A method of calibrating a servo reader and a read/write head for a data storage tape machine that reads and writes data to a data storage tape. The data storage tape has a servo pattern that is recorded on the tape in a known location. The servo pattern is used to provide precise position information for the data storage tape. According to the method, data is recorded on the data storage tape and the location of the data storage track is read. The location of the data storage tape is compared to the known location of the servo pattern to establish a reader offset value. The data storage tape machine is updated based upon the reader offset value to adjust the position of the read/write head.

A method and apparatus for reducing tape media edge damage in data regions. The present invention controls where popped strand occur by shifting the wrap turn around/stream points in the tape media to an unused region of tape. As data is written for the length of the tape, when a wrap turn around point is reached, the write current is shut off. However, the servo motors in the tape drive continue to stream the tape for a predefined distance past the turn around point. The head may then be moved transversely to acquire a new track. The tape may then be spooled in the reverse direction on the new track. When a wrap point is encountered, the write current may be turned on and the next track (wrap) may be written. This combination of steps may be repeated for each serpentine wrap on the tape.

A method and system for transmitting tape cartridge information using a bi-axial tape cartridge antenna design. A contactless tape cartridge memory device is provided in which the memory device is accessible from multiple surfaces of the cartridge. A single flexible antenna surrounds the tape cartridge memory device. The antenna may be bent to fit within the corner of the tape cartridge, thus providing a parallel antenna surface to two locations on the cartridge, such as the front of the cartridge and the side or bottom of the cartridge. As a result, the memory device in the tape cartridge may be read when the cartridge is being inserted into the tape drive as well as while the cartridge is stored within the tape drive.

A timing based servo alignment system that uses a set of band identification marks to determine which data band is being currently read. The system uses a read module having a plurality of band identification read elements. The band identification read elements are placed on the read module such that each band identification read element is aligned only to the band identification marks when a corresponding data band is aligned to the data read element.
