Claim 8:
9. The method according to claim 2, wherein after the step of magnetizing the rubber layer to make the rubber layer magnetic and before the step of baking the rubber layer within the predetermined time under the predetermined temperature to make the magnetic poles of the rubber layer stable to obtain the magnetic data line, the method further comprises:
winding the rubber layer that is magnetic and the plurality of metal wires in a fixture to enable the rubber layer that is magnetic to form magnetic rings, wherein each of the magnetic rings defines a first side and a second side; the first side of each of the magnetic rings is adjacent and opposite to the second side of an adjacent magnetic ring of the magnetic rings;
wherein the step of baking the rubber layer that is magnetic within the predetermined time under the predetermined temperature to make the magnetic poles of the rubber layer stable to obtain the magnetic data line comprises baking the rubber layer wound in the fixture within the predetermined time under the predetermined temperature.
