摘要： An apparatus for recording an information signal in a track on the record carrier is disclosed, such as a helical scan videorecorder. The apparatus comprises an inuput 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 and a writing unit (30, 32, 34) for writing teh converted information signal in the track on the record carrier. Further, a unit for establishing the total length of the record carrier, viewed in time, a unit for establishing the actual position of the writing means along the record carrier, viewed in time, and a unit (5, 6) for transporting the record carrier is present. For recording an information signal of specific duration (T2), on said 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 (T2) of the information signal to be recorded.

摘要： A linear tape system (50) has a tape head (54) to read and write a linear data storage tape. As the tape moves in a longitudinal direction, the tape head senses magnetic transition stripes in longitudinal servo bands to control the lateral position of the tape head relative to the tape. The system is equipped with a linear speed calculating unit (58) that derives timing data from the servo band stripes and computes a linear speed of the data storage tape in the longitudinal direction. The linear speed calculation produces a result that is independent of the lateral position of the tape head relative to the tape.

摘要： When, during the replay of the VTR (10), time codes are sent to the control unit (60) and the special part detection device (30) supplies detection data to the control unit, the control section (66) displays an indication of the special parts being detected and the time codes found and transferred at detection time on the display device (72) and the video monitor (20), and writes the detection data and the corresponding time codes into the memory (70). Hence, the contents of the special parts detected in the reproduced video (tape scratch, flicker, special pattern or change in average luminance, and the levels of these) and the time codes found and transferred at detection time are stored, thus enhancing the efficiency of the editing of cutting off the special parts.

摘要： A timing recovery system for the lower density longitudinal record channels utilizing capstan velocity or feed forward rate in a magnetic tape recording/reproducing system in which the capstan feed forward velocity, derived from an encoder (20, provides a signal whose frequency is proportional to the speed of the tape (10) driven by the capstan (14). A scaling circuit is provided by means of a frequency-to-voltage converter (40) followed by a voltage-to-frequency converter (44), the output signal providing a demodulation clock having a multiplied frequency proportional to the data rate reproduced from the tape. The demodulation clock, fed to timing window generation circuitry (50), provides an input to data detection circuitry to provide a clocked data output, regardless of the reproduce speed within a very large range of speeds.

摘要： A spindle sync control system for a plurality of magnetic disk drives connected in parallel to a host computer. The system is capable of reducing lost time and preventing a system from going down. The system includes a discriminator (25A) for discriminating the presence or absence of a reference index, a medium index and a Hall index; an offset calculator (25B) for calculating an offset value between the medium, index and Hall index before starting spindle sync control; a memory means (26) for storing the thus calculated offset value; a phase difference calculator means (25C) for calculating a phase difference between the reference index and the medium index; and a determination means (25D) for determining a driving control value for rotating a spindle motor (7) according to the thus calculated phase difference.
