ABSTRACT:
A magnetic linear scaling device including a stationary base and a magnetic scale secured to the stationary base. The magnetic scale has a track including a detection area in which magnetic scale data is recorded. A magnetic head is so disposed as to be movable along the magnetic scale in an opposed relation thereto. The magnetic head detects the magnetic scale data recorded in the detection area of the track. A resin tape covers at least the detection area of the track to protect the magnetic scale data from being damaged. The resin tape has a first surface attached to the magnetic scale and a second surface opposed to the magnetic head.
