摘要：
An information recording medium of this invention has a spiral track. The spiral track has one or more header fields per round of the spiral track, and a data field located between neighboring header fields. The data field has a variable length corresponding to an integer multiple of a predetermined length Lw so as to minimize a deviation between the n-th header field in a predetermined round of the spiral track, and the n-th header field in a round different from the predetermined round in the track direction.
