摘要： In an optical disk device using an optical disk of a single land/groove spiral configuration, headers dividing each track revolution into sectors have one or more mirror surface parts, and the disposition and/or length of the mirror surface parts is different between sectors at a connecting point and sectors which are not at a connecting point. The device includes a circuit for detecting a connecting point based on the position and/or length of the mirror surface part. The device is further provided with a circuit for predicting the connecting point, thereby making up for any failure of detection by the detecting circuit. Such a predicting circuit may have a circuit for predicting the connecting point based on the phase of the disk motor when a connecting point is previously detected, or alternatively a circuit for predicting the connecting point by counting the number of PLL clocks, from a sector preceding the sector which is at a connecting point.

摘要： In an optical disk of a single-spiral configuration, and including a first sequence of address pits and a second sequence of address pits, wherein headers include first and second sequences of address pits provided in different positions along the track. The first sequence of address pits are shifted by half a track pitch in a first radial direction so that its center line is aligned with a first boundary between a land track and a groove track following the header. The second sequence of address pits are shifted in a second radial direction opposite to the first radial direction by half a track pitch so that its center line is aligned with a second boundary (next to the first boundary) between a land track and a groove track following the header. The first sequence of address pits indicate an address of a sector in a first one of a land track and a groove track following the header. The second sequence of address pits indicate an address of a sector in a second one of a land track and a groove track following the header. The disk may further comprises mirror surface parts provided following the first and second sequences of address pits in a header at the connecting point. The offset in the tracking error signal is detected when the light spot is scanning the sequences of address pits and/or the mirror surface parts.

摘要： A base transceiver station includes a baseband signal processor outputting a frequency notification signal indicating a carrier frequency for modulating a baseband signal, in combination with a baseband signal and a radio transmitter and receiver modulating the baseband signal from the baseband signal processor with the carrier frequency designated by the frequency notification signal so as to produce a radio transmission signal. By allowing the baseband signal processor to output the baseband signal and the frequency notification signal to the radio transmitter and receiver, the radio transmitter and receiver is immediately informed of the carrier frequency for modulation of the arriving baseband signal so that the radio transmitter and receiver is capable of generating a radio transmission signal efficiently and properly.

摘要： In an optical disk of a single-spiral configuration, and including a first sequence of address pits and a second sequence of address pits, wherein headers include first and second sequences of address pits provided in different positions along the track. The first sequence of address pits are shifted by half a track pitch in a first radial direction so that its center line is aligned with a first boundary between a land track and a groove track following the header. The second sequence of address pits are shifted in a second radial direction opposite to the first radial direction by half a track pitch so that its center line is aligned with a second boundary (next to the first boundary) between a land track and a groove track following the header. The first sequence of address pits indicate an address of a sector in a first one of a land track and a groove track following the header. The second sequence of address pits indicate an address of a sector in a second one of a land track and a groove track following the header. The disk may further comprises mirror surface parts provided following the first and second sequences of address pits in a header at the connecting point. The offset in the tracking error signal is detected when the light spot is scanning the sequences of address pits and/or the mirror surface parts.
