摘要： In a signal reproducing device such as an R-DAT video tape recorder, a digital signal recorded on the recording medium is reproduced by the magnetic head, stored in a memory, processed by a processing circuit, and converted into an analog signal by a D/A converter, and a detector detects whether or not the reproduction signal outputted by the head is present so that, according to the output of the detector, a muting circuit mutes the digital-to-analog converted signal and a driver suspends the operation of a level meter adapted to display the level of the digital signal, whereby the production of noise signals and the abnormal display of signal levels are prevented.

摘要： A signal recording/reproducing apparatus having both bar-type and numeric signal-level displaying units which can be easily read. The apparatus includes a sample-and-hold circuit for sampling and holding an input signal at a first predetermined rate, a first display unit for displaying in bar form the sample values sampled by the sample-and-hold circuit, a data holding circuit for sampling and holding the sample values periodically at a second predetermined rate, and a second display unit for numerically displaying the sample values selected by the data holding circuit. The bar code display can change at a rapid rate to dynamically follow the input signal, while the numeric display changes at a slower rate so as to allow the user sufficient time to comprehend the numerically displayed value.

摘要： In a stereo sound digital recording system in which a plurality of tunes or programs are sequentially and digitally recorded on a magnetic tape, the left and right analog input signals are combined and converted to a digital signal. The analog input signals are also applied to a detector which detects the head of the program or tune and which causes to be generated a start identification sub-code signal which is automatically added to the digital signal, before the modulation thereof, and which is recorded on the tape for about nine seconds in the non-sound portion preceding the tune or program. A second sub-code signal, in the form of a program number signal, may also be added to the digital signal, simultaneously with the program start identification sub-code signal, to provide recorded numbers respectively identifying programs which are sequentially recorded on the tape.

摘要： The present invention relates to a position detecting apparatus for and method of detecting a position of a transport unit, wherein the transport unit is used to pick up a designated disk from a disk container containing a plurality of disks to transport the disk thus picked up to a disk playback unit. The present invention accumulates the number of pulses output by an encoder of the transport unit as the unit moves upward or downward along an encoder channel. The accumulated count is used as a position count for determining the position of the transport unit between the disk container and the playback unit. A second encoder generates a pulse train corresponding to the movement of the transport unit along the second encoder channel. The second encoder channel having a plurality of recesses spaced at a wider pitch than in the encoder channel. A comparison between the level of the pulse train generated by the second encoder and the odd or even number of accumulated pulses output by the encoder indicates whether or not pulse output has been missed. If it is determined that a pulse output has been missed, the transport unit is moved to a predetermined position, and the position count is reset to a number corresponding to the predetermined position.

摘要： A system for positioning a pick-up head of a disk player at a predetermined point having an address determining circuit to determine the position of the pick-up head. A calculating circuit determines the distance to a target position on the basis of the address detected. A controller provides a move output signal to displace the pick-up head at high speed to the target position. The address (location) of the head is again determined and a second move operation performed to plan the pick-up within a predetermined range so that a search for the target address can be performed.
