Additional Information

• Actual storage capacity of storage products such as USB drives, memory cards, hard drives, and optical discs may be slightly less than the stated capacity due to manufacturer algorithms differing from those of the operating system.
• Manufacturer's standard: 1GB = 1,000MB, 1MB = 1,000KB, 1KB = 1,000 bytes
• Operating system's algorithm: 1GB = 1,024MB, 1MB = 1,024KB, 1KB = 1,024 bytes
• Normal capacity discrepancies for optical discs: 700MB~700MB; 4.7GB~4.38GB; 8.5GB~7.92GB; 25GB~23.29GB; 50GB~46.59GB
• The speed indicated on discs is the theoretical recording speed (e.g., 1-16X), meaning the maximum speed can reach 16X, not the standard speed. Speeds like 1-2X, 1-4X, 1-8X, 1-52X have similar meanings.
• Various factors can affect recording speed, such as laser head aging, computer settings, compatibility between the recorder and the disc, and lack of high-speed support by the recorder.
• It is recommended not to record at the maximum speed to maintain recording quality and success rate.
