ABSTRACT:
Information is recorded with one or more elongate thermal recording heads on a recording medium advancing at least intermittently on a recording medium support. Such recording head or heads are being pressed against the recording medium at the recording medium support by at least two biasing devices spaced along such elongate thermal recording head or heads. These two biasing devices are balanced relative to each other opposite the elongate thermal recording head or heads, as seen from the recording medium support. Different characteristics of the biasing devices are thus compensated opposite the elongate thermal recording head or heads, as seen from said recording medium support. Forces acting at one end of an elongate thermal recording head, or acting on one of the recording heads, against either of the biasing devices are transmitted via both biasing devices to an opposite end of that elongate thermal recording head or to the other of two elongate thermal recording heads. Movements of the recording medium support at either end of one elongate thermal recording head, or at one of the recording heads, are transmitted via the biasing devices to an opposite end of that elongate thermal recording head or to the other of two elongate thermal recording heads for perfect balance.
