US 6,552,986 B1 · Apparatus for recording and reproducing data

Abstract

A data recording and reproducing apparatus includes a recording disabled state determining device for determining whether or not the optical disc is in a recording disabled state, in which the data recording and reproducing apparatus controls the rotation of the optical disc to increase a rotational speed during reproduction processing higher than the rotational speed during recording processing to reproduce data when the recording disabled state determining device determines that the optical disc is in the recording disabled state, thereby accepting a recording instruction and a reproduction instruction as required at any time, and avoids reproducing data at the same reproducing speed as a recording speed which is unnecessarily slower than the reproducing speed.

Dependent claims

A data recording and reproducing apparatus for recording and reproducing data while controlling the rotation of an optical disc, comprising:

control means for comparing a first time period required for reproduction processing when data is reproduced while a first rotation control is performed for said optical disc, with a second time period required for the reproduction processing when data is reproduced from said optical disc while a second rotation control is performed for said optical disc, to select said first rotation control for reproducing data when said first time period is shorter than said second time period, and to select said second rotation control for reproducing data when said second time period is shorter than said first time period.
