  • Bis(hydroxylkyl)disiloxanes and lubricant compositions thereof
    Patent number: 4391720
    Abstract: Bis(hydroxyalkyl)disiloxane lubricants of the formula ##STR1## wherein R.sub.1 and R.sub.3 are methyl or ethyl and R.sub.2 and R.sub.4 are linear alkyl groups of up to 20 carbon atoms. These compounds are useful as additives to methyl alkyl siloxane lubricants for conductive high density information discs. Discs lubricated with the lubricant mixture exhibit improved stability to environments of high temperature and high relative humidity.

  • Spinel video disc playback stylus
    Patent number: 4370739
    Abstract: An improved information storage and playback system comprising a playback stylus and a disc record. The information is recorded in the surface of the disc record and there is relative motion between the disc and the playback stylus during recovery of the recorded information. The stylus is fabricated out of a dielectric support material and contacts the record disc surface during the recovery of the information. The improvement comprises employing a playback stylus whose dielectric support material is single crystal magnesium aluminate spinel. The spinel composition comprises a ratio of MgO to Al.sub.2 O.sub.3 of from about 1:1 to about 1:2.5.
