Method and apparatus for determining and using head parameters in a helical scan recorder |
摘要 |
Methods and apparatus are provided for determining a servo offset value and a take-up reel velocity for imparting a desired linear velocity to tape in a helical scan recording system (20). The helical scan recorder system records information on a magnetic tape (22), the magnetic tape being transported between a supply reel (24) and a take-up reel (26) in the helical scan recorder through a tape path, which tape path includes at least a partial wrapping of the tape around a drum (30) of the helical scan recorder. The methods include moving the tape from the supply reel to the take-up reel whereby the tape travels a predetermined displacement; rewinding the tape by the tape extraction displacement and determining an angular rewind displacement of the take-up reel; and using the determined displacements to ascertain parameters including a desired velocity of the take-up reel. |
