Title: Tracking device for optical disc memory
Inventor: SAITOU FUJIO
IPC: G11B7/085
Filed: 1981-07-20
Abstract: PURPOSE:To make tracking possible without a pregroup, by generating a signal for the radius of a light scattering material on a basis of a detected Doppler shift quantity and comparing this signal with a control signal designating the radius position to lead a head to the designated position. CONSTITUTION:An output signal 221 from a photodetector 319 is separated into a read signal 332 and a Doppler signal 333 by a BPF341. A control signal 338 for track selection is converted to an analog voltage signal, and a signal having a frequency corresponding to this voltage is generated by a voltage control oscillator 36. A signal of the sum or the difference between frequencies of this signal and a signal from a quartz oscillator is transmitted as a reference signal 337 of a frequency corresponding to a desired track. The Doppler signal 333 and the reference signal 337 are sent to a comparator 35 to output an error signal 334. The error signal 334 is sent to a driving mechanism 322 to position an optical head 32 onto the desired track. Thus, tracking of the optical head is realized without a pregroup.

Abstract: PURPOSE:To realize the line connection device for a card terminal equipment in which the line connection is reduced when a card is verified with a host computer through the use of a public communication line such as a telephone line in the service system employing an ID card or the like. CONSTITUTION:Every time an ID card is once in use, its occurrence time data (day, time, minute, weekday) is recorded and stored by a CPU 2. Then the CPU 2 decides a time zone when the ID card is frequently in use in excess of a prescribed frequency of use. Then the card terminal (automatic ending machine 1) is connected directly to a telephone line 12 for the time zone. Thus, the transmission of the data recorded on the card is implemented in a short time for the use of the card for the time zone and the processing speed for card verification or the like is quickened thereby preventing a customer from being kept waited long. Furthermore, in the case of using the card for a time other than the time zone, since the number of customers is less, it is coped with the method that the line connection is implemented for each occasion.
