Multi-channel recording head, image recording method and image recording apparatus

摘要

The multi-channel recording head includes a plurality of recording channels (22a-22e) arranged in one direction, and spare channels (24a-24e) arranged away from the recording channels by an integral multiple of the channel pitch of the recording channels on the extension of an array of the recording channels. The spare channels (24a-24e) are arranged as least as many as the number of the recording channels (22a-22e), and each spare channel has the same physical resolution as the resolution of an image to be recorded. The physical resolution of the multi-channel recording head is lower than the resolution of the image. The image recording method and the image recording apparatus record the image by using the above multi-channel recording head.
