A magnetic recording medium comprising a flexible support, a first recording layer, an intermediate layer and a second recording layer in this order, wherein the second recording layer comprises a ferromagnetic metal alloy comprising Co, Pt and Cr, and a nonmagnetic oxide. The method comprises receiving medical information of a patient located at a location different from the intensive care unit, evaluating conditions of the patient by applying one or more rules to the medical information of the patient, and sending a message to the intensive care unit when the conditions of the patient match the one or more rules. Detection of failing memory units may be via current, voltage andor resistance monitoring. To avoid larger capacitors, a pulse multiplier circuit can be added, allowing chargingdischarging the sampled voltage to the target voltage to be repeated by a number, N, of times.
