Abstract
A burst cutting area of an optical recording disc includes a BCA mark comprising a plurality of pits over which a reflective layer is formed. The plurality of pits may be arrayed according to a pit pattern specifying a predetermined nominal positional relationship between adjacent pits. The pit pattern may comprise microstripes which include one pit per pit track and most adjacent pits in adjacent pit tracks. A direction between adjacent pits within each of the microstripes may correspond to a nominal microstripe direction which may form an angle with a pit track direction within a range of 45° to 135°.
