TECH TOPIC - extract from 1972 issue
"Phono Cartridges"
For a while, designers of reproduction systems smiply made the stylus do what they wanted it to by increasing the tracking force until the stylus had to put in the groove. This had its obvious disadvantages; and though today they still recognize the dilemma, designers have been learning what the problems are and finding better ways of circumventing them than by the use of brute force.

Compliance
"As the stylus rides in the groove of a record, there is a great deal of actual contact pressure between the two. This pressure is a result of nothing more than the applied tracking force in an un-modulated groove. When the groove starts pushing the stylus around, contact pressures can rise considerably above 24 tons per square inch and the amount of rise depends on how much the stylus resists the grooves' efforts to move it. When the resistance to movement is significant, groove destruction does take place, and the stylus starts to rattle around between groove walls ot produce the familiar shatter of tracking distortion

Most specifications give a figure for compliance which is expressed in terms of the distance in 10-6cm the stylus is displaced by a 1 dyne force (roughly 1mg). Modern magnetic cartridges boast up to 20 x 10-6 cm/dyne or more."

Tidbits
(Unverified)

RRB would record the news from the BBC for broadcasting. During the Merdeka riots of 1967 RRB was forbidden to broadcast any item pertaining to the riots. Time magazine was banned from the country during that time also.

A series of talks and music exercises for pregnant mothers was broadcast for a short while by RRB. However local authorities deemed it was not suitable for public broadcast in that area and transmission ceased. I am told that the last words spoken on this series were to the effect of: "This was the last programme, but never mind, we've had a swell time."
