An improved switching regulator .Iadd.DC-DC power converter or .Iaddend.power supply with a variable duty cycle is disclosed which forms part of a compact Winchester disk drive system having a storage capacity in excess of 380M bytes of information. The switching regulator is designed for frequencies in excess of 80 kilocycles per second and may therefore be construced using smaller capacitive and inductive elements. Also, very low heat dissipation and high regulator efficiency may be achieved by the improved .Iadd.power converter or .Iaddend.power supply to drive a brushless D.C. motor encased within a hard disk assembly where no separate fan or cooling system is used to aid in heat removal. Circuitry is provided to control the motor speed while simultaneously limiting the motor current to a predetermined level. This is a achieved by controlling the voltage applied to the motor by suitably adjusting the duty cycle of the switching regulator. A filter is provided to ensure that the switching regulator current fluctuations are not reflected in the current drawn from the power supply. At the start when the D. C. motor E.M.F. is zero, the switching regulator causes significantly higher current to flow through the motor than is drawn from the power supply through a current multiplying effect. These unique features provides significant advantages in a Winchester disk drive using thin film media whose overcoming high level of initial stiction-friction forces .Iadd.between the read/write heads and the recording media .Iaddend.is important and desirable.

MAGNETIC RECORDING AND/OR REPRODUCING APPARATUS ABSTRACT OF THE DISCLOSURE In recording periodic information signals, such as, the chrominance signal components of color video signals, having first or field intervals which are further subdivided into second or line intervals and which are recorded in successive parallel tracks on a record medium, interference or cross-talk between signals recorded in adjacent tracks is reduced or eliminated during reproduction by recording the information signals in adjacent tracks with first and second carriers having different frequencies Upon reproducing the information signals recorded in adjacent tracks with such first and second carriers, the reproduced signals are reconverted to have a common carrier frequency by means of respective first and second reconverting signals which similarly have different frequencies selected so that, although an information signal reproduced from a particular track and reconverted to the common carrier frequency will pass through a comb filter, the cross-talk signals reproduced simultaneously from adjacent tracks will be reconverted to have carrier frequencies at nodes of the comb filter so as to be eliminated by the latter The circuits by which the first and second carriers and the first and second reconverting signals are produced during recording and reproducing operations, respectively, each include a phase-locked loop having a voltage-controlled variable frequency oscillator whose output frequency is suitably changed in successive field intervals, and preferably in which the center frequency of the voltage-controlled variable frequency oscilator is also changed in the successive field intervals for obtaining rapid stabilization of the respective output frequency ?

A video signal recording apparatus of reduced size for portability combines a video camera and helical scan video tape recorder in a single unit, in which the reduced size is obtained in part by having a tape guide drum of reduced diameter, which requires a tape wrap angle greater than the conventional 180° and employs a pair of rotary tape heads that are arranged close together relative to the diametrically opposed conventional head arrangement The timing of the heads in recording the fields of the video signals as tracks is controlled by a vertical synchronization signal having pulses that are delayed to account for the finite distance between the two rotary heads The vertical sync signal then has a different time period for a first field than it does for a second field of one frame of the video signal The camera has an image pickup portion that is caused to be scanned by the same synchronization signals utilized in the recording operation This permits any horizontal overscan to occur at a time when the heads are off the tape and by adjusting the time base of the vertical sync signal the overscan can be arranged so that the portion of it is above and below the effective portion of the image pickup portion of the camera

Video signal recording apparatus

A video signal processing circuit includes an amplifier with a circuit connected to it to emphasize the amplification of some frequencies relative to others. A non-linear circuit is also connected to the amplifier and comprises a capacitor connected in series with non-linear elements that change the amplification of positive and negative overshoots of the signal relative to the middle amplitude range. The result is non-linear modification of emphasis and can be used to pre-emphasize video signals before using them to modulate the frequency of a carrier and, in the playback section to de-emphasize the signals to minimize FM noise. Use of the capacitor prevents direct current from flowing and thus affecting the threshold levels of the non-linear elements. Component values can be selected to effect temperature compensation.

Capacitive-type nonlinear emphasis circuit

Apparatus for recording and/or reproducing a SECAM composite color television signal in parallel tracks on a record medium. The luminance and chrominance components of the SECAM television signal are separated from each other, and then the luminance component is modulated to a higher frequency range while the chrominance component is frequency-converted to a lower frequency range. These frequency-modified components are recombined and recorded. In frequency-converting the chrominance component, first and second frequency-converting carrier signals are generated, and the phases of these frequency-converting signals are synchronized, or locked, to the incoming SECAM television signal so as to exhibit corresponding phase changes. When these frequency-converting signals are used to frequency-convert the chrominance component of the SECAM television signal, the resultant frequency-converted chrominance components are recorded in at least one track with a substantially constant phase and in the next adjacent track with a frequency-converted sub-carrier which differs from that of the said one track. The recorded frequency-converted sub-carrier frequencies in adjacent tracks are in frequency interleaved relation with respect to each other. In one embodiment of the recording apparatus, the frequencies of the frequency-converting signals differ from each other by n/4fh, wherein n is an integer (preferably 1) and fh is the horizontal line frequency of the SECAM television signal. In this embodiment, the phase of the recorded chrominance subcarrier is constant for all tracks.

Secam recording and reproducing system

TITLE"VIDEO SIGNAL RECORDING AND REPRODUCING APPARATUS AND METHOD" In a VTR for use with SECAM signals, the signals are recorded in H-alignment in a plurality of parallel tracks on a record medium in a configuration such that field intervals in which the same chrominance component (i.e. B-Y or R-Y) occurs in successive tracks are aligned to reduce the effect of crosstalk. To avoid difficulties arising in stop and slow motion reproduction where the heads may scan a path which is skewed relative to the tracks, the chrominance components in every other frame are delayed by lH by a delay line prior to recording while the chrominance components in the remaining frames are delayed by 1H by a delay line . To ensure correct sequencing of a switch, associated with the second delay line a tone-burst from an oscillator is inserted during the vertical blanking period of every fourth frame.
