DETERMINING ANGULAR POSITION OF A TAPE REEL USING TIMING BASED SERVO FORMAT |
摘要 |
Provided are techniques for determining an angular position of a tape reel. A first edge of a hall sensor is identified. A number of format transitions on a timing based servo formatted tape are counted until detecting a predetermined edge of the hall sensor. A reel circumference is determined. A radius is determined using the determined reel circumference. A new circumference of a next revolution is determined using the determined radius and a tape thickness. A current angular position is determined using the determined new circumference and the counted format transitions.
