reference servo pattern writing method of high-capacity magnetic media driving apparatus for self-servo writing and device for the same

PURPOSE: A reference servo pattern generating method is provided to write or read data on the basis of a servo pattern, which is recorded by a driving apparatus itself, without recording an embedded servo pattern on a record medium. CONSTITUTION: In a reference servo pattern generating method, if a self servo writing operation is requested, a magnetic head is transferred to a position according to corresponding data on the basis of head transfer data which is stored in a ROM(S101,S103). Data remaining on a magnetic disk is deleted(S104), and the magnetic head is returned to an initial position(S105). If the magnetic head is returned to an initial position, a servo pattern stored in the ROM is accessed(S106), and whether an index pulse is generated from a spindle motor is judged(S107). If so, the accessed servo pattern is recorded in synchronization with a frequency generator signal generated from the spindle motor(S108). The recorded servo pattern is read out, and the magnetic head is shifted finely at the same time(S109). Data is read through a head corresponding to the half track shift, and data read through a head, which exists at another plane, is recorded at the same time(S110). Whether servo information is recorded with regard to all regions is judged(S110). If not, the procedure goes to the step(S109). If so, the program is ended.
