An apparatus for detecting wobble information of an optical disc and a method thereof are disclosed. The assembly also includes at least one corresponding ink jet print head chip carrier that defines an elongate recess having a pair of opposed side walls. The second region is of the second conductivity type and is formed in the first well. The connection circuit guarantees the associated processor a higher minimum guaranteed access frequency to said associated one of the memory banks than to a further one of the memory banks other than the associated one of the memory banks.
