Optical disk having R/W and worm area |
摘要 |
An optical storage arrangement is provided where a unified optical disk, or other optical media, has separate Read/Write (R/W) and Write Once Read Many (WORM) areas. A Read/Write head or transducer selectively records data only once in the WORM area but records and re-records data in the R/W area. Both areas can be selectively read repetitively. The WORM area is used to store data records and the R/W area contains directories for the data records recorded in the WORM area.
