摘要： An information recording/reproducing device and a medium are improved in reliability by making medium managing information usable even when a defective sector exists in the medium managing information area of the medium. The identifier of medium managing information, the information about the position where the medium managing information is recorded which is the information about the position of the sector in use, or the information about the position where a defect exists in the medium managing information area, which is the information about the position of the defective sector, are read from the medium managing area of the medium (3) and all the information is stored in a RAM (8) by using a medium managing information position manager. A reproducer and a recorder are controlled based on the information. Therefore, the medium managing information is correctly recorded and the reliability of the data of the information recording/reproducing device and the medium is improved, because the medium managing information is not recorded in the defective section.

摘要： In a manifold apparatus having a plurality of functions including a printer function, facsimile function and copier function, facsimile data from a host computer are transferred to a system controller via a printer controller. Information on the destinations for facsimile communication are registered at an image memory. The system controller searches the image memory on the basis of destination data contained in the facsimile data, thereby determining whether the destination has a G3 function or a G4 function. If the destination has a G3 function, the system controller transforms the facsimile data to image data and transmits the image data via a facsimile controller. If a G4 function is available at the destination, the system controller transmits the facsimile data, or code data, without transforming them.

摘要： A disk nearly constant in recording density from the outer circumference to the inner circumference of the disk, such as CLV and M-CAV format, is rotated at a constant angular velocity to read out information, and the information being read in at a varying read transfer speed depending on the position on the disk from the optical pickup is stored once in a buffer memory. The information stored in the buffer memory is sent out at a constant send transfer speed. When reproducing from a disk-shaped recording medium nearly constant in recording density in the inner and outer circumference, the disk information is read at a constant rotating angular velocity, and the information varying in read transfer speed depending on the disk position is outputted at a constant send transfer speed suited to the reproduction of information such as voice and picture. The host computer or the like for controlling the apparatus is not required to distinguish the type of medium or recording format, or perform processing such as control of the transfer speed. Furthermore, when outputting the stored information, means for setting the send transfer speed by an external device or switch inside the apparatus is provided. By this means, the information can be reproduced at a transfer speed suited to the content of the information being handled.
