Abstract: The invention provides a positioning servo mechanism suitable for use in positioning the magnetic heads in a magnetic disk memory, and in which an actuator is driven in response to algebraically summed signals representing commanded position, actual position, and velocity. 
     In a disk memory the head position may be determined by counting track crossings, giving a signal which has a fluctuating component and cannot be differentiated to give a usable velocity signal. 
     In the present invention a coarse velocity signal is generated by integrating and amplifying a signal representing actuator current. The coarse velocity signal is integrated between successive track crossings to give a coarse distance signal. This is compared with a signal representing the actual distance between tracks, and the difference is used to adjust the gain of the amplifier, so correcting the coarse velocity signal at each track crossing. A further correction my be obtained by adding to the input of the first integrator an accumulative error correction signal representing the change in amplifier gain.

IPC: H04J3/04
Filed: 1979-12-04
Abstract: An adaptive delta modulation system is disclosed which features an improved digital compandor which may be used with a digital integrating network. The compandor executes a companding algorithm having a nonlinear characteristic to provide a rapid increase in step size to follow the fast rising start or fast decaying end of talkspurts in input signals so as to minimize any slope overload distortions and to provide a small increase or decrease in step size during the smooth portion of the talkspurts in input signals to reduce any granular noise effect. The step size generated by the compandor is directly related to the input signal level, providing a maximum companding range in which good signal-to-noise characteristics are preserved for the soft or low voiced speaker as well as for the loud voiced speaker and providing a fast transient response most suitable for telephone applications. The step size logic of the compandor has a built-in minimum step size circuit which insures that a well behaved idle pattern of alternating ones and zeros will appear at the digital output when the input signal is zero, and which provides a mechanism to rapidly build up the step size when an input signal appears. The step sizes can be integrated with an integrating network to reconstruct the input signal. The compandor may be used in conjunction with a digital integrating network which exhibits, for example, a system function, having either a single pole or a zero and a pair of poles which may be real or complex. The filter constants can be chosen to match any input spectrum to obtain optimum performance. A significantly high signal-to-noise ratio and a wide companding range have been obtained with the disclosed compandor. By providing storage elements in the compandor and in a digital integrating network and storing the calculated intermediate values, a plurality of input for output analog signals can be time division multiplexed and delta modulated with a single delta modulation system.
