Doubly Journaling Store Method For Storing Data in Storage Medium

PURPOSE: A doubly journaling storage method for storing data in a storage medium is provided to separate meta data from general file data, and to store the file data from the first position of a storage medium, then to store the meta data from an end position to the first position of the storage medium, thereby quickly accessing the data. CONSTITUTION: A system sets initial values to '0'(S101). If a storage request is received in a storage medium(S102), the system confirms whether storage spaces are sufficient(S103). If so, the system confirms whether a central point is '0'(S104). If so, the system confirms whether received data is front journaling data(S105). If so, the system stores the data. The system confirms whether the stored data meets a rear portion head(S106). If not, the system performs a rear part in symmetrical to a front part(S107). If the stored data does not exceed the rear part head, the system stores the data(S108).
