  • Patent number: 8332608
    Abstract: For decreasing seeks generated when switching an execution flow between commands to enhance read and write performances of a disc drive, a command is implemented with a specifically-designed data structure, and commands having neighboring physical addresses and the same type of read or write operations are grouped and linked together. With the aid of command groups, seeks between commands are significantly decreased, though starvation may arise. A few techniques are further provided for preventing starvation of command groups and for preserving the benefits of decreasing seeks.
