Peristaltic pump assemblies in which the closing and opening of a pivoting or sliding door is coordinated with movement of the occlusion bed toward and away from the rotor assembly to engage and disengage tubing within the occlusion pathway are disclosed. With this, a situation that the actuator is pressed as being twisted is eliminated to achieve an excellent action of pinching the signal transmission medium and an easy and reliable visual check of the state of rotation of the actuator. The plurality of recording and reproduction conditions are arranged in the order of time at which the plurality of recording and reproduction conditions are recorded. Methods for making the article include provide either providing a monolithic substrate having a first magnetic polarity, or applying a first magnetic field to the monolithic substrate to impart a first magnetic polarity.
