摘要： An optical tape decoding system includes a decoder that may apply a matched pattern signal (72) representing an address index to a track address signal (74)including a multi-cycle wobble block representing the address index such that a signal is output having a peak corresponding to the multi- cycle wobble block. The decoder may also identify the address index based on an amplitude of the peak.

摘要： Signal transmission system equipped with a transmitter (11) and a receiver (12). The transmitter (11) has first clock extract means (13, 14) which detects synchronizing signals contained in a first DAI format signal from the receiver (12), and which generates first clock signals of a predetermined frequency whose phase is locked to the synchronizing signals; a data read means (4) which reads the data from a recording medium on the basis of the first clock signals; and a first encode means (5) which encodes the data from the data read means (4) into a second DAI format signal on the basis of the first clock signals. The receiver (12) has second clock extract means (6, 7) which detects synchronizing signals contained in the second DAI format signal and which generates second clock signals of a predetermined frequency whose phase is locked to the synchronizing signals; a decode means (8) which decodes the data from the second DAI format signal on the basis of the second clock signals; an oscillation means (3) which generates master clocks; a D/A conversion means (9) which converts the demodulated data from the digital signals into analog signals on the basis of the master clocks; and a second encode means (15) which encodes the master clocks to obtain the first DAI format signals. The system is operated in synchronism by the master clocks, whereby the digital/analog conversion is carried out at a timing of clock signals not containing jitter.

摘要： Amplitude or phase modulated un-compensated wobble patterns representing address patterns for track addresses of optical media are generated. A filter is applied to the un-compensated wobble patterns to pre-compensate the un-compensated wobble patterns. When an inverse of the filter is applied to a signal representing the pre-compensated wobble patterns in the presence of noise, the noise is suppressed and the un-compensated wobble patterns are substantially recovered.
