摘要： A control apparatus of a real time counter for a video cassette recorder. This apparatus comprises a CLOG detection section having an envelope detector, a comparator, and a low-pass filter for detecting a CLOG signal to judge whether a signal exists on the videotape; an ATF detection section having an ATF detector, an analog-to-digital converter, a band comparator, a shift register, and a state detector for detecting an automatic track following signal, an AND gate for performing a logical product between the CLOG signal and the automatic track following signal and an REC instruction; and a counting section having a switch which is for controlling a real time counter using the output, or a control signal of the AND gate. This apparatus accomplishes the accurate control of a counting by using an automatic track following signal as well as the CLOG signal.

摘要： An optical disc recording device is disclosed in which RF signals reproduced from a write-once optical disc are detected during track jump for detecting the boundary between a recorded area and an unrecorded area on the write-once optical disc. This defines a roughly defined boundary between the recorded and unrecorded areas which may be searched quickly. A more strictly defined boundary between the recorded and unrecorded areas, may be searched quickly by subsequently employing a binary search method to the roughly detected boundary.

摘要： An apparatus for recording an information signal in a track on the record carrier, such as, a helical scan video recorder, includes an input terminal (36) for receiving the information signal, a signal processor (10) for converting the information signal into a form in which it can be recorded on the record carrier (1) and a writing unit (30,32,34) for writing the converted information signal in the track on the record carrier. Further, the apparatus includes a unit for establishing the total length of the record carrier, viewed in time, a unit for establishing the actual position of the writing unit along the record carrier, viewed in time, and a unit (5,6) for transporting the record carrier. For recording an information signal of specific duration (T.sub.2), on the record carrier (1), the record carrier is transported to a specific position along the record carrier for which holds that the remaining time for recording, at that specific position, substantially corresponds to the specific duration (T.sub.2) of the information signal to be recorded.

摘要： Disclosed is a circuit for detecting an unrecorded portion of a recording medium, which has a window counting portion (10) for receiving an input signal, for recognizing if the input signal comes from an unrecorded portion of the recording medium and for counting a predetermined time to generate a window signal. The circuit also has a sync signal generator (20) which is enabled by the window signal, in which, if the number of pulses of the input signal equals or exceeds a predetermined number, the generator recognizes that the current input signal comes from a data region of the recording medium and therefore generates a sync signal. If the number of pulses of the input signal is less than the predetermined number of pulses, the generator recognizes that the current input signal is due to noise from an unrecorded region of the recording medium, and therefore does not generate the sync signal. The unrecorded portion is accurately detected since no sync signals are generated due to noise included in the unrecorded portion of the recording medium.
