Document Type and Number:
Japanese Patent JP4211158
Kind Code:
B2
Abstract:
A recording/reproducing apparatus comprising an OP head 11 , a wobble circuit 12 , a system controller 13 , and an address-decoding timing generator 14 . The wobble circuit 12 extracts a wobble signal from the signal the OP head 11 has read. A PLL circuit for generating a sync signal from the wobble signal is held while no normal wobble signal is generated. The address-decoding timing generator (Address DEC TG) 14 receives a signal the OP head 11 has reproduced, decodes the address represented by the signal, and supplies the address data to the system controller 13 . The generator 14 also generates a timing signal from the sync signal supplied from the wobble circuit 12 and supplies the timing signal to the other components of the recording/reproducing apparatus.
