Abstract:
A method of accessing information recorded on a disc medium, using a disc drive which comprises a pickup head and a buffer memory,wherein said pickup head reads the information from said disc medium and supplies the read information to said buffer memory with a given physical transmission rate referred to as PTR, said buffer memory temporarily stores the read information from said pickup head and outputs the stored information with a given system transmission rate referred to as STR, and assume that N represents an upper limit of count of access by said pickup head to said disc medium within a unit time, that JATa represents an average jump access time of said pickup head, and that MWTa represents an average rotation wait time of said disc drive, then said N is determined in accordance with said PTR, STR, and MWTa and said N is less than 1/(JATa+MWTa).
