Optical servo system for a tape drive |
April 15, 2003 |
| The optical servo system for a tape drive that functions to align a read/write head with the data tracks written on a recording surface of a tape by reading optical servo tracks that are formed on the back side of the tape. This process decouples the magnetic recording of data on the |

System for minimizing the effects of scratches on recording media |
December 9, 1997 |
| A system is disclosed which significantly reduces the susceptibility of a recording media to data loss due to scratches. The system uses a signal generator function to inject a periodic, small amplitude dither signal into the head positioning servo system during a write or preformatting |
