摘要： PROBLEM TO BE SOLVED: To construct a system by which copyright and personal information are appropriately protected and also, a user can freely obtain desired contents at low cost and in a short time. SOLUTION: Contents are preliminarily stored in a recorder 1 and enciphered based on an identifier attached inherently to a medium M, and the enciphered contents are recorded on the medium M. Limitation conditions needed to reproduce, display or perform the contents are further recorded on the medium M. A object device 2 decodes the contents recorded on the medium based on the identifier, and reproduces, displays or performs the contents under the limitation conditions recorded on the medium M.

摘要： PROBLEM TO BE SOLVED: To compensate for aberration by detecting individual aberration due to each aberration cause. SOLUTION: A laser light is converged by an objective lens 6, projected to a magneto-optical disk 1 and reflected. The reflected light is polarized into P and S waves by a phase beam splitter 9, the P wave is fed to a push-pull tracking control unit 90, and the S wave is fed to an aberration compensating unit 10. The aberration compensating unit 10 includes a photodetector 11, a tracking control unit 12, a thickness/focusing control unit 13 and a tilting control unit 14. The photodetector 11 receives the S wave, and computes and outputs a control signal to be fed to each control unit. Signals are respectively outputted from the tracking control unit 12, the thickness/focusing control unit 13 and the tilting control unit 14, thereby the objective lens 6 is moved such that respective control signals become zero.

摘要： PROBLEM TO BE SOLVED: To provide a modulation device which can eliminate a modulation pattern being not suitable for a transmission system and a modulation pattern being weak for a demodulation system. SOLUTION: In this modulation device, a bit serial signal is divided into blocks for each prescribed length, bit serial signals being different one another and having equal bit length are added to the divided blocks, the prescribed '1' or plural times of conversion processing are performed for each block to which the bit serial signal is added, a block is selected out of each block in which conversion processing is performed depending on the prescribed conditions, and the selected block is outputted as a bit serial signal modulating the selected block. The device is provided with an at least one setting circuit 1 setting the prescribed pattern of a bit serial signal, plural detecting circuits (4a-4p) detecting a pattern set by the setting circuit 1 out of each block in which conversion processing is performed, and an eleminating circuit 16 eliminating the block when the detecting circuits (4a-4p) detect the pattern.

摘要： PURPOSE:To improve the degree of freedom for waveform shaping processing of a reproduced signal. CONSTITUTION:The variable filter circuit 1 is provided with a differential sum/subtraction type equalizer 2 waveform-shaping a reproduced signal. The sum subtraction coefficient of the differential sum/subtraction type equalizer 2 is divided to almost independently control the amplitude characteristic and the delay characteristic to attain waveform shaping. A low pass filter 3 is connected to the equalizer 2 and when the amplitude characteristic is made flat, the variable filter circuit 1 is approximated entirely to the Butterworth type. In addition the slope of the delay characteristic is controlled variably almost in the middle of the flat part.

摘要： PURPOSE:To attain synchronizing pull-in with a margin even at a start of an input signal by synchronizing an input signal at its input forcibly at a wide lock range through frequency/phase difference comparison and oscillating a signal for a prescribed time at a prescribed period with phase comparison at the end of input signal. CONSTITUTION:At the input start of the input signal, a PLL circuit is synchronized with the input signal forcibly at a wide lock range via a frequency/phase difference comparison means (frequency/phase comparator) 60. Moreover, at the end of input signal, the synchronization with the input signal for a prescribed period is kept by the phase comparison via a phase comparator 1. Thus, the synchronization pull-in with a margin is attained even at the input signal start and the frequency is changed gradually to the self-running frequency at the end of input signal.
