摘要： Übliche Recorder zeichnen Datenpakete auf, deren Format an das Datenformat des Recorders angepaßt ist. Haben die Datenpakete jedoch ein abweichendes Format, ergeben sich verschiedene Schwierigkeiten, z.B. mit dem Fehlerschutz. In solchen Fällen ist daher auch kein Suchlauf-Mode mit einer zumindest partiellen Auswertung von Datenpaketen vorgesehen.
Erfindungsgemäß werden darum die Datenpakete vor der Aufzeichnung/Speicherung entsprechend Fig. 1 'quer' angeordnet, d.h. es wird nicht jedes Datenpaket (1, 2, 3, 4, 5) fortlaufend aufgezeichnet/gespeichert (in vertikaler Richtung in Fig. 1), sondern es wird fortlaufend der erster Abschnitt (a) der Datenpakete aufgezeichnet (in horizontaler Richtung in Fig. 1). Anschließend werden die weiteren Abschnitte dieser Datenpakete aufgezeichnet. Beim schnellen Suchlauf eines digitalen Recorders können die Schrägspuren aber nur abschnittsweise gelesen werden. Von den Datenpaketen (1...5) würden nur Rudimente erfaßt, die für die Wiedergabe nicht sinnvoll decodiert werden können. Es werden nun in bei einem Suchlauf zusammenhängend lesbaren Reserve-Abschnitten zusätzliche Datenpakete (A1, A2, B1, B2) aufgezeichnet, die auch teilweise Kopien von den bereits auf 'normale' Weise aufgezeichneten Daten sein können. Beim Suchlauf mit erhöhter Geschwindigkeit werden dann diese Reserve-Sync-Blöcke ausgewertet.

摘要： In a system for recording and reproducing digital signals on a magnetic tape (12) using a rotary head (11 A, 11 B), in which the signals are recorded as a series of slanted tracks (14A, 14B) without guard bands between adjacent tracks (14A, 14B), a pilot signal that was recorded during the recording process is used to control the tracking of the playback head (11 A, 11 B). The pilot signal is recorded at a specific position in a specific pilot signal record region, independent from the region of the track (14A, 14B) at which the information signal is recorded, and the pilot signal is arranged at a predetermined position or positions being a specified distance from an end of each track (14A, 14B) in its longitudinal direction, and only alternate tracks receive the pilot signal. When the recorded tracks (14A, 14B) are reproduced by a rotary playback (11 A, 11 B) having a tracing width that is greater than the width of the track (14A, 14B), the pilot signals from the adjacent tracks (14A, 14B) will be detected and can be compared in level, with the comparison output being used to control the tracking of the rotary playback head (11 A, 11 B).

摘要： The rotary head type helical scanning magnetic tape recording and reproducing apparatus is provided with an auxiliary recording head (5a,6a,5b,6b) for recording pilot signals adjacent to a main head (3a,4a,3b,4b) for recording a signal to be recorded, and an auxiliary reproducing head (la,2a,1b,2b) for reproducing the recording pilot signals. The pilot signals recorded to an antecedent track are reproduced by the auxiliary reproducing head (1a,2a,1b,2b) at the time of recording to the next track. A tracking control of the main (3a,4a,3b,4b) head at the time of next track recording is effected according to the reproduced pilot signals.

摘要： In a helical scan recording system, magnetic tape (31) is transported by a tape transport (98) proximate a rotating scanner (85). The scanner has a pair of read heads (82) mounted thereon, e.g., a first read head and a second read head, which travel in a helical direction on the magnetic tape in view of the transport of the tape and rotation of the scanner. A synchronization detection system (38) determines a first synchronization mark detection time at which a first synchronization mark is read by the first read head from the first track, and a second synchronization mark detection time at which a synchronization mark read by the second read head from the second track. A position error signal generator (100) develops a position error signal (PES) based upon a difference between the first synchronization mark detection time and the second synchronization mark detection time. The servo or transport controller (98) uses the position error signal to develop a servo correction signal for adjusting the position of the read heads. In accordance with one aspect of the present invention, a first distance separating the sync marks along the helical direction of head travel is sufficiently less than a second distance by which the read heads of the pair are circumferentially separated on the scanner to render the position error signal (PES) immune to any variation in the rotational speed of the scanner. In accordance with another aspect of the invention, the position error signal generator comprises a coarse position error signal generator; a fine adjustment signal generator; and a combination element. The combination element combines a course position error signal and an adjustment signal to obtain the position error signal PES which is used by the servo controller to keep the read heads traveling along a longitudinal centerline of their respective tracks.

摘要： A format for the recording of trick play signals in which trick play segments including sync blocks of information of a trick play signal are recorded in the tracks. At least first and second trick play signals are recorded on the record carrier. The first trick play signal is meant for reproduction in a reproduction apparatus at a reproduction speed n1 times the recording speed with which the trick play signals are recorded on the record carrier. The second trick play signal is meant for reproduction in the reproduction apparatus at a reproduction speed −n1 times the recording speed. Both trick play signals are recorded in the tracks such that, upon reproduction at the speed n1 times the recording speed, m1 sync blocks of information of the first trick play signal and, upon reproduction at the speed −n1 times the recording speed, m1 sync blocks of the second trick play signal are read from the record carrier during one revolution of the head drum in the reproduction apparatus. Further, a direction identifier is stored in the trick play sync blocks, indicating whether a trick play sync block is meant for a specific trick play speed in the forward or in the reverse direction.
