Abstract
In order to reduce emission noise, a recording apparatus uses a cycle controller to variably control a transmission cycle, when transmitting recording data to the recording head, and a head controller to control the recording head based on the controlled transmission cycle and the recording data. By varying the data transfer cycle of data to the recording head, the recording apparatus of the present invention makes it possible to suppress a rise in radiation noise peak levels due to overlapping of radiation noise spectra, which in turn weakens the strength of the electric field at certain cycles and makes it possible to reduce radiation noise levels.
Claims8
A recording apparatus which performs recording, having a recording head, over a recording medium based on information transmitted by an external apparatus, the recording apparatus comprising:
- a cycle control unit adapted to variably control a transmission cycle, when transmitting recording data to the recording head;
- a head control unit adapted to control the recording head based on the controlled transmission cycle and the recording data.
