Title: Recording digital information signals
IPC: C07F9/6558
Filed: 1985-08-01
Abstract: in a system for recording and reproducing digital signals on a magnetic tape (2) using a rotary head (1A, 1 B), in which the signals are recorded as a series of oblique tracks (5A, 5B) without guard bands, a pilot signal that controls tracking alignment of a playback head (1 A, 1 B) is recorded at a particular position in a specific pilot signal record region, different from the information signal record region. An erase signal having various recording lengths is also recorded in the pilot signal region such that a start position of the erase signal corresponds substantially to a centre portion of the pilot signal on the adjacent track (5A, 5B). When the recorded tracks are reproduced by a playback head (1 A, 1 B) having a tracing width greateer than the track width, the pilot signals from the adjacent tracks (5A, 5B) will be sampled by sampling pulses generated in response to the reproduced erase signal and compared in level, and the comparison output will be used to control the tracking alignment of the playback head (1A, 1B).

Abstract: A programmable oscillator includes first and second 
transistors having their emitters coupled by a capacitor, and 
a pair of current sources coupling respective transistors to 
ground. A switching means is provided having a first state 
coupling the collector of the first transistor to the base of the 
second transistor and coupling the collector of the second 
transistor to the base of the first transistor, and a second 
state coupling the collectors of the first and second transis­
tors to ground such that when the switching means is in the 
first state, the first and second transistors switch on and off 
in alternating fashion, and when the switching means is in 
the second state the first and second transistors remain on 
continuously. Means are provided to hold the base of the 
first transistor at a high logic level and to hold the base of the 
second transistor at a low logic level while the first switching 
means is in the second state, to couple a third current source 
to the collector of the first transistor while the second 
transistor is off and to the collector of the second transistor 
while the first transistor is off, and to prevent the switching 
means from switching from the first to the second state until 
the base of the first transistor is at a higher voltage level than 
the base of the second transistor.

Abstract: A distributed balanced frequency multiplier 11 has a 
transmission line 25 that is configured using lumped 
elements having connection points 29 for inputting 
signals. Connected to each connection point is the 
output from a non-inverting amplifier 19 which amplifies 
a signal applied thereto. A second transmission line 27 
is configured also using lumped element 13 techniques and 
has connection points 42 for receiving an inverted 
amplified signal whose odd harmonics are 180° to the 
non-inverting amplified signals. The signal that is to 
be amplified is carried to both the non-inverting and the 
inverting amplifier by a third transmission line 29 that 
also uses lumped elements 13 distribution techniques to 
create a transmission line. The output of the first 
transmission line and the second transmission lines are 
tied together so that the odd harmonics due to the 
inverting amplification stages cancel and the even 
harmonics are additive, thereby achieving an effective 
multiplication of the input signal.
