An optical storage medium comprising:
a lead-in area, which comprises a read only area and a readable/recordable area;
a user data area in which user data is recorded;
a first wobble formed in the read only area of the lead-in area; and
a second wobble formed in the readable/recordable area of the lead-in area;
wherein the user data is transferred with respect to the user data,
the first wobble is modulated by a first modulation method and the second wobble is modulated by a second modulation method different to the first modulation method, and further an apparatus for transferring data with respect to an optical storage medium comprising a lead-in area, which comprises a read only area and a readable/recordable area, and a user data area in which user data recorded, the apparatus comprising:
an optical pickup to emit light to transfer data on the storage medium; and
a controller arranged to control the optical pickup to record data on the user data area,
wherein user data is transferred with respect to the user data area,
first data with respect to a first wobble formed in the read only area of the lead-in area is transferred,
second data with respect to the readable/recordable area, in which a second wobble is formed, of the lead-in area is transferred,
the first wobble is modulated by a first modulation method and the second wobble is modulated by a second modulation method different to the first modulation method.
