摘要： PROBLEM TO BE SOLVED: To increase surface recording density of write-once recording by narrowing track pitch even if a yaw angle is changed by a rotary actuator.
SOLUTION: In the write-once storage device, a head provided with a recording element and a reading element is supported at a tip of a rotary actuator 15, and reproduction is performed after information is written in a disk medium once by the head. In a writing processing part 46, information is written successively from a track where the yaw angle of the actuator in a recording track area of a disk medium becomes the maximum to a track where the yaw angle becomes 0. For example, in the writing processing part 46, information is written from the outermost track of the disk medium to a track where the yaw angle is 0, next, information is written successively from an innermost track to a track where the yaw angle is 0. In a reading processing part 48, Information written in the disk medium is read out from a track where the yaw angle is large to a track where the yaw angle becomes small.

摘要： PURPOSE:To display securely a highly-advanced control function and to improve the operability by providing a control means for giving a control signal which shifts a reproduction drive means to a central position between the 1st and 2nd disk mounting parts so as to stand by based on the detection signal of a clamp un-completion given from a detection means. CONSTITUTION:A microprocessor 201 judges through an I/O interface circuit 203 whether or not disks with respect to a disk A mounting part 110 and disk B mounting part 111 are clamped by a mechanical unit 200 based on the detection signal from a mechanical unit up limit switch 236 for becoming a clamp detection means, for instance. If the judgement is NO, a control signal is supplied to a movable motor 230 through the interface circuit 203 having a function as an external control circuit in order to shift and stand by the unit 200 to the central position between the A/B disk mounting parts 110 and 111.

摘要： PURPOSE:To eliminate a drive of a DC motor for feeding for not long time longer than required even if a tracking error signal is disordered by muting the output of a comparator at every prescribed period. CONSTITUTION:Comparators 2, 3 input a tracking signal from a tracking servo circuit 25 for controlling a pickup 22, and output signals when the pickup 22 tilts at the outer or inner peripheral side of disc-shaped information recording medium 21. A control signal of H level is applied to a terminal 6 or 7 or control signals of H and L levels are alternately applied to the terminal 7 or 6 at normal reproducing time. A controller 4 supplies the output of the comparator 3 or 2 to the control logic input terminal of a motor drive circuit 11 only when the control signal is H level.

摘要： PURPOSE:To inhibit a movement that is carried out in accordance with an error data even though a code of type II has an error by detecting the shifting frequency of a pickup toward the inner and outer circumferences of a disk to compare both frequencies with each other and then inhibiting the movement of the pickup carried out based on the detection data if no correspondence is obtained to the direction of reproduction. CONSTITUTION:An extracting circuit 40 extracts code data X5 and X6 out of a gate 36, and the OR is compared with X5 by a comparator 45. A pulse P2 is delivered if the data X5 and X6 have an error. Thus the movement is inhibited for a control circuit 41 even though a pulse P1 is delivered. When the pulse P2 is not delivered, an AND is obtained by a logical circuit 47 for data X5 and X6. A detecting circuit 48 detects the movement frequency m1 of a pickup toward the inner circumference of a disk; while a detecting circuit 49 detects the shifting frequency m2 toward both inner and outer circumferences respectively. A subtractor circuit 50 detects the shifting frequency m3 toward the outer circumference, and a subtractor circuit 51 delivers m4. A deciding circuit 52 delivers a pulse P3 when m4>=1 is satisfied and delivers no p3 with m4 =1 and accepts them in the case of m4
