Abstract

A data recording apparatus includes a storage unit, a control unit, and a card interface unit. The storage unit stores master data being original data of data to be recorded on a card-type medium. The control unit reads out the master data from the storage unit and executes a recording processing control of the read-out master data with respect to the card-type medium. The card interface unit installs the card-type medium therein and executes data recording processing. Further, the control unit executes, in parallel to recording processing of the master data with respect to the card-type medium, error verification processing of the master data to which the verification value stored in the storage unit is applied, and performs a control of stopping the recording processing of the master data with respect to the card-type medium when an error is detected.

Description

technical field [0001] The present disclosure relates to a data recording device, a data recording system, a data recording method, and a program. Specifically, the present disclosure relates to a data recording device, a data recording system, a data recording method, and a program that realize early detection of occurrence of data writing errors and error reduction. Background technique [0002] Many disc-mounted media such as digital versatile discs (DVD) and Blu-ray Discs (BD) have been utilized as media for recording images, audio or game programs, and the like. In recent years, the use of card-type memories such as flash memories has rapidly increased. [0003] When producing a large number of discs storing the same content, a large number of many discs can be continuously manufactured using a stamping process based on a stamper of a master disc recording content. [0004] However, in the case of a flash memory type medium, duplication using a stamper as in the disc ...
