    Abstract: A higher-capacity disk drive system (101, figure 7A) and a higher capacity removable disk cartridge (106) adapted for downward compatibility with older, lower-capacity disk drive systems, wherein a unique control format (208, figure 9C) is stored on higher-capacity removable disk cartridges (106) to distinguish them from older, lower-capacity removable disk cartridges (104) and thereby to facilitate cartridge capacity recognition by the higher-capacity disk drive system (101). Upon recognizing the capacity of an inserted removable disk cartridge, the higher-capacity disk drive system (101) can read and write data to the removable disk cartridge such that data which it stores on a lower-capacity removable disk cartridge (104) may be read by lower-capacity disk drive systems. A predefined distance between a DC gap and a servo pattern is used to determine disk storage capacity.

    Abstract: A higher-capacity disk drive system and a higher-capacity removable disk cartridge adapted for downward compatibility with older, lower-capacity disk drive systems, wherein a unique control information format is stored on higher-capacity removable disk cartridges to distinguish them from older, lower-capacity removable disk cartridges and thereby to facilitate cartridge capacity recognition by the higher-capacity disk drive system. Upon recognizing the capacity of an inserted removable disk cartridge, the higher-capacity disk drive system can read and write data to the removable disk cartridge such that data which it stores on a lower-capacity removable disk cartridge may be read by lower-capacity disk drive systems.
