An object of the present invention is to provide a laminating-printing system which can further improve the quality of laminated-printed objects. The present invention provides a laminating-printing system including a laminating-printing unit () which prints the layers and sequentially laminates the layers; and a concentration adjusting unit () which adjusts the concentration of gas components in the shield gas, the laminating-printing unit () including: an irradiation section including an irradiation source of energy rays to irradiate the powder material, and a printing section including a chamber filled with the shield gas and a printing stage on which the layers are printed and laminated, and the concentration adjusting unit () including: a purification section which removes a first gas component which is an impurity in the shield gas based on the powder material; and a supply section which supplies a second gas component selected based on the powder material inside of the chamber as needed.

Laminating-printing system and laminating-printing method

There is provided a recording apparatus that records data to a memory card, comprising: a control unit configured to repeatedly transmit a data recording instruction that includes information designating recording target data and a recording destination to the memory card which manages a memory for data recording in the memory card as a plurality of recording areas and which can execute data recording with a guaranteed minimum recording speed in units of recording areas, wherein when transmitting a first data recording instruction that designates a start portion of a first recording area as a recording destination, the control unit requests the memory card to execute data recording with the guaranteed minimum recording speed with respect to the first recording area by including a speed guarantee request in the first data recording instruction.

Recording apparatus, recording method, storage medium, and memory card

A control apparatus configured to record data in a recording medium includes a cluster management unit configured to manage clusters in a predetermined area in a recording area of the recording medium, a recording management unit configured to manage clusters in the predetermined area in recording units each having a predetermined size larger than each cluster size, and a directory cluster allocation unit configured to set a cluster in the predetermined area to a directory cluster in which a directory is recorded. The directory cluster allocation unit is configured to allocate a cluster out of clusters in a tail end area in the predetermined area to the directory cluster, the clusters in the tail end area being smaller than a size of the recording units having the predetermined size and being not managed by the recording management unit.

Control apparatus that improves recording of data in a recording medium by allocating directory clusters to recording units in a more effective manner, and control method and non-transitory computer readable storage medium storing instructions thereof

A recording apparatus that is capable of preventing degradation of a writing speed of management information under recording without increasing the recording preparation time when a plurality of files are recorded simultaneously. The recording apparatus includes a memory and a processor that function as a recording unit that records a file in a recording medium, and a controller that controls so as to record a directory entry of a file in a designated sector in the recording medium. The recording medium consists of blocks each of which includes a plurality of pages, allows to write data in a page unit, allows to erase data in a block unit, and allows to access a page corresponding to a sector designated by a sector number. When a plurality of files will be recorded, the controller controls so that directory entries of the plurality of files will be recorded in a same sector.

Recording apparatus that records data using file system, control method therefor, and storage medium storing control program therefor
