Data can be recorded onto an optical card (102; 200; 601; 800) on which a plurality of tracks are parallelly arranged and can be reproduced therefrom. The optical card is supported by card supporting means (101; 501). This card supporting means is reciprocated in a first direction by card drive means (109; 511). An optical head (103; 503; 603) is provided above the optical card to selectively provide access to tracks by a light beam. This optical head is reciprocated in a second direction perpendicular to the first direction by head drive means (108; 507). The reciprocating motion of the card supporting means is accelerated and decelerated when the optical head scans on guide sections (G) provided on both the sides of the optical card. Error correcting codes are added to data recorded onto the optical card. Thus, error correction is made by an error correction circuit (136). Motors of respective drive means are enclosed with vibration proof metal (321, 323) and vibration proof rubber (322). The card supporting means (101) comprises pressing means (423) for pressing the upper surface of the optical card and positioning means (425) which can be in contact with the side surface of the optical card and away therefrom, thus to carry out positioning of the optical card. The card supporting means (501) is provided with contact surface (501a). By roller means (506) having rotation shaft (505) slightly inclined with respect to perpendicular (505') set up on the plane including the contact surface, optical card inserted from the outside is introduced toward the contact surface. The optical head (103) is ordinarily controlled by feedback control.
