Abstract: PURPOSE:To speed up a magneto-optical storage by providing a data recording area and an alternate area on one and the same track and executing an erasing and a writing in the same cycle. CONSTITUTION:When a light command is sent from a host computer CPT 21 to a controller 20, a CPU 26 analyzes the command according to a program in a ROM 27, decides the writing area of data and transfers writing data to a buffer 23. When the data is written to sectors 2-4 of a data area 11 on the track, in a first cycle, the sectors 2-4 are erased, and sectors 7-10 of an alternate area 12 are read. Reading data are sent from a magneto-optical recorder 30 to the buffer 23. In a second cycle, the data are written to the sectors 2-4 by an inverse route and the sectors 7 and 8 are erased. In a third cycle, the sectors 2-4 are read, and when errors are generated, they are written to the area 12. In a fourth cycle, the sector 7 is read, and when the errors are generated, the writing and reading are repeated to the area 12.

Abstract: PURPOSE:To prevent the hysteresis torque of a torsional damper from growing larger by dint of friction force to be produced by which an equalizer between two torsion springs set up in a circumferential tandem rubs with other parts of the torsional damper. CONSTITUTION:While transmitting power to a torque converter 8 from an engine output shaft 2 via a torsional damper, an equalizer 11 between two torsion springs 9 and 10, through a component force from these springs, is pressed by force (f) to a side plate 5 in an annular inner circumferential part 11a, and in this pressure-contact state, the annular inner circumferential part 11a and the side plate 5 are rubbed with each other. However, a low friction plate 12 in this rubbing part reduces the extent of frictional force between this innercircumferential part 11a and the side plate 5, whereby hysteresis torque in the torsional damper is prevented from gowing larger.
