Abstract
An apparatus for aligning a moving substrate and a read or write head includes independently controllable rollers for deskewing the sensed skew of a moving substrate and a read or write device that is translatable in a direction fixed with respect to the reference direction of the moving substrate.
Claims14
An apparatus for aligning a moving substrate and a read or write head;
- said apparatus comprising:
- sensing means for sensing at least the edges of said moving substrate relative to a reference direction;
- deskewing means for deskewing said moving substrate with respect to said reference direction;
- translating means for translating said head relative to said reference direction;
- and
- controlling means for controlling said means for translating in response to said means for sensing such that a preselected segment of said moving substrate traverses said head.
