Abstract
A magnetic encoder system according to one embodiment includes a magnetic sensor mounted on a first substrate above a magnetic medium, the magnetic medium carrying at least one magnetic track, the sensor detecting changes in the magnetic track during a relative movement between the sensor and the magnetic medium. The first substrate is provided with a second substrate rotatably engaging the magnetic medium.

A magnetic encoder system, comprising:
- a magnetic sensor mounted on a first substrate above a plane of a magnetic medium, the plane extending through a majority of an outer periphery of the magnetic medium, said magnetic medium carrying at least one magnetic track, said sensor detecting changes in said magnetic track during a relative movement between said sensor and said magnetic medium,
- wherein said first substrate is provided with a second substrate rotatably engaging said magnetic medium.
A magnetic encoder system, comprising:
- a magnetic sensor mounted on a first substrate above a magnetic medium, said magnetic medium carrying at least one magnetic track, said sensor detecting changes in said magnetic track during a relative movement between said sensor and said magnetic medium,
- wherein said first substrate is provided with a second substrate rotatably engaging said magnetic medium,
- wherein the magnetic sensor is spaced from the magnetic medium,
- wherein a spacing between the magnetic sensor and the magnetic medium is variable,
- wherein the spacing between the magnetic sensor and the magnetic medium varies according to a biasing exerted on the first substrate toward the magnetic medium.
