    "abstract": "We describe an array of microscopic atom traps formed by a pattern of\nmagnetisation on a piece of videotape. We describe the way in which cold atoms\nare loaded into one of these micro-traps and how the trapped atom cloud is used\nto explore the properties of the trap. Evaporative cooling in the micro-trap\ndown to a temperature of 1 microkelvin allows us to probe the smoothness of the\ntrapping potential and reveals some inhomogeneity produced by the magnetic\nfilm. We discuss future prospects for atom chips based on microscopic\npermanent-magnet structures.",
