<p>Bytes of data are read from or written in sectors (S) on a movable record medium (D) containing non-data areas in one or more sectors (S). At least one useful data-length (RLC) count is provided in at least one RLC field (105', 107', 109') in a sector, each RLC count representing the length of a respective useful data region (105, 107, 109) in that sector. The RLC count is read from the RLC field (105', 107', 109') and data is read from or written in the sector for a length determined by the RLC count which was read. The reading or writing of data is interrupted for a predetermined length when a non-data area (106, 108) is encountered; and the read or write operation is resumed following that predetermined length.</p> |
