There is disclosed an optical information recording medium having phase-change recording films whose the transmittance can be made substantially uniform irrespective of the presence or absence of recording. The LOG image sensor generates an output in response to the light, with the output voltage being a logarithm of the intensity of the light received. A home version of the system may be formed with a home computer and a database storing garment images in cooperation with a manufacturer. An incremental wait time is waited in response to determining that the queue is in the waiting phase. In addition, the incision tensioners allow the incision to have a known geometry, thereby allowing precise grafting of the graft vessel to the target vessel during the anastomosis procedure.
