    摘要: A record carrier (1) comprises essentially circular tracks (20) concentrically located around a point of rotation (2). The record carrier (1) is divided into circular zones (4, 5, 6) comprising each m tracks (22), with m being an integer. Each track within a zone is subdivided into n sectors (8), with n being an integer which is constant per zone and which increases as the zone is more remote from the point of rotation (2). Each sector (8) comprises a header portion (9) and a data portion. The header portions (9) in radial direction in each zone are in line. In each zone the condition of m.n = l.k is satisfied, with l being an integer greater than or equal to 2 and being constant for each zone, and with k being an integer.
