Applicant: TANDBERG DATA STORAGE A/S , LIAN, Ragnar , SIMONSEN, Lars , RUDI, Guttorm
Inventor： TANDBERG DATA STORAGE A/S
IPC: G11B05/584
CPC classification number: G11B5/584 , G11B5/5504
Abstract: The present invention resolves the problem of micropositioning reading/writing heads quickly and precisely in relation to tape on a tape streamers, at the same time as the reading/writing head can be displaced across the complete width of the tape. At the same time it will have small stray field of magnetism which potentially can destroy tape and reading/writing heads.
Abstract translation: 本发明解决了在磁带机上与磁带相关地快速且精确地定位读/写头的问题，同时读/写头可以跨越磁带的整个宽度移位。 同时它将具有小的杂散磁场，这可能会破坏磁带和读/写头。

Abstract: In methods and arrangements for concentrating stray magnetic fields, a pair of permanent magnets is employed in combination with a magnetic flux circuit, the permanent magnets in the pair having respective magnetizations that are oriented oppositely to each other. The permanent magnets produce a stray magnetic field that adds to a magnetic field produced by the magnetic flux circuit.
