Title:
FORMAT FOR RECORDING DATA ON A STORAGE DISK
Document Type and Number:
WIPO Patent Application WO2001093262
Kind Code:
A3
Abstract:
A data storage disk includes a writeable area (12) that allows a user to write data, wherein the data files are written from the outside diameter towards the inside diameter of the writeable area (12), while file system information (120) is written from the inside diameter towards the outside diameter of the writeable area (12). This optimizes the use of the writeable area, whether a large number of small data files or a small number of large data files are being stored. To further optimize the use of the writeable area (12), information may be stored in two or more different error correction code (ECC) block sizes. Thus, information, such as the file system attributes and linking sectors, which contains few bytes may be stored in the smaller ECC block size, while the data may be stored in the larger ECC block size. The data storage disk may also include a mastered content area.
