1. Field of the Invention
The present invention relates to an information recording apparatus or an information recording system which can write information into a CD-R/RW (Compact Disk-Recordable/Rewritable), DVD-R/RW (Digital Versatile Disc-R/RW), magnetic optical disc, magnetic disc (such as a hard disc or a floppy disc), memory card (RAM), or tape and which can be used as a replaceable medium for a computer system. Further, the present invention relates to an information recording medium or a computer readable recording medium that stores a program causing a microcomputer or host to execute software.
2. Description of the Related Art
Other objects, features and advantage of the present invention will become more apparent from the following detailed description when read in conjunction with the accompanying drawings, in which:
FIG. 1 is a block diagram of a drive apparatus according to a first embodiment of the present invention;
FIG. 2 is a schematic flowchart of an interrupt control process executed in the drive apparatus shown in FIG. 1;
A description will be given, with reference to FIGS. 1 through 3, of a first embodiment of the present invention. An information recording apparatus according to the first embodiment of the present invention is applied to an information recording/reproducing apparatus capable of handing a CD-R/RW 1, which is a recordable optical disc used as an information recording medium. FIG. 1 is a schematic block diagram of a configuration of the information recording/reproducing apparatus (drive apparatus).
The optical disc 1 is rotationally driven by a spindle motor 2, which is controlled by a motor driver 3 and a servo unit 4 so that the optical disc 1 can be rotated at a constant linear velocity (CLV). An optical pickup 5 includes a semiconductor laser diode, an optical system, a focusing actuator, a tracking actuator, a light-receiving element, a position sensor and so on, and projects a laser beam onto a recording surface of the optical disc 1.
The optical pickup 5 can be moved in a sledge direction (radial direction of the optical disc 1) by a seek motor. The embedded focusing actuator, tracking actuator and seek motor are controlled by the motor driver 3 and the servo unit 4 that use signals obtained from the embedded light-receiving element and position sensor so that the laser spot can be placed at a target position on the optical disc 1.
