摘要： An apparatus is disclosed for positioning a head (34) relative to a plurality of tracks (T1, Tn) running parallel to each other in their longitudinal direction on a record carrier (1). First and second tracks (T1, T2) have first and second tracking signals (S1, S2) of specific frequencies recorded in them and third and fourth tracks (Tn-1, Tn) have third and fourth tracking signals (Sn-1, Sn) of specific frequencies recorded in them. The apparatus comprises a head (34) for reading the tracking signals, control signal generator means (36, 38) for generating a first control signal in response to the first and second tracking signals (S1, S2) and for generating a second control signal in response to the third and fourth tracking signals (Sn-1, Sn). A positioning unit (40, 42) for moving the head (34) in a direction transverse to said longitudinal direction, has an input for receiving said first and second control signals and for moving the head in response to said first and second control signals, so as to position the head (34) onto a fifth and sixth track (Ta, Tz) respectively. A position detection unit (48, 49, 56) for detecting the position of the head (34) in said transverse direction, has an output (58) for supplying a first and a second position signal when the head (34) is positioned onto said fifth and sixth track (Ta, Tz) respectively. In a calibration mode of operation the position of the fifth and sixth tracks are located and the generated first and second position signals are stored in a memory (60).

摘要： The invention relates to a system comprising a magnetic tape (310) formatted by means of a write head (360), and an apparatus comprising a magnetic head unit (320) which is movable on a transverse direction (y) by means of an actuator. By means of the write head (360) the magnetic tape (310) has been provided with a pattern of servotracks ST101-ST127 which extend in a longitudinal direction (x). The odd-numbered servotracks contain a first servosignal and the even-numbered servotracks contain a second servosignal Sb which is phase opposition to the first servosignal. The servotracks ST103-ST113 and ST116-ST126 have a typical width W1 and form a group of two bands of N1 servotracks which are separated by a band of N2 servotracks ST114, ST115 having a typical width W2. The magnetic tape (310) is adapted to cooperate with an apparatus comprising eight magnetic write heads (H31-H38). The actuator is controlled in response to the servosignals read by the heads. The center-to-center distance (p) between the magnetic write heads (H31-H38) is equal to four times the typical width W1 and, moreover, it holds that: N2 = 2, 4, 6 etc. and W2=(k+1/2)W1 or N2 = 1, 3, 5 etc. and W2=2k.W1, where k = 1, 2 etc.

摘要： The invention thus relates to the identification of lead-in and lead-out portions of a longitudinal record carrier (2), using marks in the form of a modification of tracking signals (s1, s2) recorded in tracks (T1, T2). This identification is such that the frequencies of the tracking signals remain unchanged in the lead-in and the lead-out portion. Such modification results in the possibility to use the tracking signals in the lead-in and the lead-out portion to record an information signal even in a part of the lead-in and the lead-out portion. The modification may be realized by changing the duty cycle of the tracking signals.
摘要翻译：因此，本发明涉及使用记录在轨道（T1，T2）中的跟踪信号（s1，s2）的修改形式的标记来识别纵向记录载体（2）的导入和导出部分。这种识别使得跟踪信号的频率在引入部分和引出部分中保持不变。这种修改导致即使在引入部分和导出部分的一部分中也可以在引入部分和引出部分中使用跟踪信号来记录信息信号。可以通过改变跟踪信号的占空比来实现修改。

摘要： For the clock extraction (Cln) from n digital signals read from each of n tracks (Ta.1 to Ta.n) there are provided n phase-locked loops (13.n). The voltage-controlled oscillator (21) is common to the n phase-locked loops. A phase-locked loop further comprises a phase-shifter unit (25.n) having an input coupled to the output of the voltage-controlled oscillator (21) and an output coupled to the second input of the phase comparator (17.n) in the loop. The phase shift in the phase-shifter unit (25.n) is controlled under the influence of a control signal which is derived by a control signal generator (26.n) and applied to a control signal input (29) of the phase-shifter unit (25.n). The control signal generator unit (26.n) is an integrating element.
