A memory controller for reading data stored in a nonvolatile memory that includes a number of erasable blocks containing a number of pages. A logical/physical address control table stored in a logical/physical address control table block of the nonvolatile memory is searched, read, and manipulated in the nonvolatile memory.

Memory controller and method for managing a logical/physical address control table

A non-volatile memory including a logical/physical address control table for controlling data recorded discretely in the non-volatile memory composed of a plurality of blocks each serving as a data deletion unit and including adjacent pages which each have a fixed length and serve as a data read/write unit. An operand data block includes operand identification data that indicates data stored in the operand data block is, in fact, operand data. The logical/physical control table block located in the non-volatile memory includes control-table identification data that indicates that data that is stored therein is, in fact, control table data that includes logical addresses and physical addresses.

Non-volatile memory storing address control table data formed of logical addresses and physical addresses

A method and apparatus for reproducing a plurality of main data recorded on an insertable recording medium in the desired sequence specified as a playlist by the user. Main data is recorded on a record region of the recording medium and the user can select a playlist that is recorded in a management region of the recording medium.

Method for editing a playlist to read main data in a desired reproduction sequence

A drive apparatus wherein a plurality of media each including a memory element can be successively accessed to continuously write and/or read out data into and/or from the media includes a loading device for loading a plurality of storage media such that data are individually written into and/or read out from the storage media, an accessing circuit for accessing the storage media loaded in the loading circuit to write and/or read out the data into and from the storage media, and a controller for controlling, when the plurality of storage media are loaded in the loading circuit, the accessing circuit to continuously perform writing into and/or reading out from the plurality of storage media loaded in the loading circuit.

Device, system and method for accessing plate-shaped memory

A method of processing original still picture data representing an original still image and stored in a video memory and storing processed still picture data representing a processed still image in a predetermined location of the video memory comprising the steps of setting an XY orthogonal coordinate system on the video memory, setting a reference line parallel to one of the X and Y axes of the orthogonal coordinate system and passing through a point of intersection of lines, each of which connects corresponding pixels of the original and processed still images, moving multiples the pixel data on a line of the original still image parallel to the reference line and furthest from the reference line to addresses of the video memory forming a line of the processed still image, and repeating the preceding step for pixel data on lines of the still image parallel to the reference line and second furthest from the reference line and succeeding lines, to thereby store the processed still picture data representing the processed still image in the video memory. An apparatus employing this method for processing original still picture data is also provided.
