Abstract: An information recording apparatus includes a first acquiring element that acquires both control information for controlling the order of recording or reproducing recorded information and virtual reference information that can be determined by the control information and by an address indicative of the position of a recording area in which the recorded information is recorded, a first converting element that converts the acquired control information and virtual reference information to first control information, a recording element that at least records the recorded information, a first control element that controls the recording element to record the converted first control information, a second acquiring element that acquires the recorded first control information, a second converting element that converts the acquired first control information to second control information having different attributes, and a second control element that controls the recording element to record the converted second control in

Abstract: An information recording apparatus (300) comprises a first acquiring means that acquires both (i-1) control information (UDF-VAT) for controlling the order of recording or reproducing recorded information and (i-2) virtual reference information (VAT) that can be determined by the control information and by an address indicative of the position of a recording area in which the recorded information is recorded; (ii) a first converting means that converts the acquired control information and virtual reference information to first control information (which is an element of UDF Bridge: File System—UDF 1.

Abstract: A pickup is moved in the radial direction of a partial CD-R, and the end position of a recorded area in the partial CD-R is detected based on a feature signal (on track signal) in the radial direction obtained during the movement. Information recorded in the recorded area is reproduced based on the detected end position, so that an accessing inability can be avoided, and the information in the recorded area can correctly be reproduced. Thus, information recorded in the partial CD-R can correctly be reproduced.

Abstract: This invention provides an operation explanation apparatus that makes it possible to sufficiently explain the operation of necessary control buttons 108 using easy operations.
