Apparatus for recording and/or reproducing information on/from optical card-like information recording medium

An apparatus for recording/reproducing optical information on and/or from an optical card in which the optical card and an optical head are relatively moved with respect to each other in a track direction and a tracking direction to record and/or reproduce optical information on and/or from said optical card, said apparatus comprising:

• driving means for causing a relative movement of said optical head and said optical card with respect to each other;
• anomalous condition detection means for detecting a condition of said relative movement between the optical card and the optical head and for deriving from said condition of said relative movement an output indicating whether said condition of said relative movement is anomalous;
• control signal production means, responsive to said output from said anomalous condition detection means, for producing at least one control signal;
• and
• control means, responsive to said at least one control signal from said control signal production means, for controlling said apparatus in accordance with the control signal produced in said control signal production means, wherein:
• said anomalous condition detection means comprises a relative moving speed detection means for detecting the relative moving speed of the optical card and the optical head and a relative moving speed range setting means for setting a first moving speed range of the relative moving speed of the optical card and the optical head when optical information is recorded on the optical card and a second moving speed range of the relative moving speed of the optical card and the optical head when optical information is reproduced from the optical card;
• said control signal production means produces a control signal when said relative moving speed for recording optical information is outside the first moving speed range or when said relative moving speed for reproducing optical information is outside the second moving speed range;
• said control means controls the apparatus so as to inhibit to record and/or reproduce optical information on/from the optical card in response to the control signal;
• and
• said first moving speed range is smaller than said second moving speed range.
