Abstract
A method and apparatus are described for forming a pattern including one or more markings on a substrate. The method includes the step of forming each marking by locally heating the substrate, for example using a fibre laser. A step is also performed of monitoring the temperature of the substrate, e.g. using a temperature sensor, whilst each marking is being formed. The method may be used to form a magnetic encoder scale on a stainless steel substrate having a high content of martensitic material. The local heating causes the martensitic material to be transformed into austenitic material. An encoder scale made using the method is also described.
