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

A recording apparatus that records data to a memory card, comprising at least one processor and/or at least one circuit which functions as:

• a control unit configured to repeatedly transmit an NVMe standard-compliant write command that includes information designating recording target data and a recording destination to the memory card which can execute data recording with a guaranteed minimum recording speed,
• wherein when transmitting a first write command 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 setting 1 at a Sequential Request bit in a Dataset Management field of the first write command.

A recording method executed by a recording apparatus that records data to a memory card, comprising:

• repeatedly transmitting 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, and
• when transmitting a first data recording instruction that designates a start portion of a first recording area as a recording destination, requesting 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.

A recording method executed by a recording apparatus that records data to a memory card, comprising:

• repeatedly transmitting an NVMe standard-compliant write command that includes information designating recording target data and a recording destination to the memory card which can execute data recording with a guaranteed minimum recording speed;
• and
• when transmitting a first write command that designates a start portion of a first recording area as a recording destination, requesting the memory card to execute data recording with the guaranteed minimum recording speed with respect to the first recording area by setting 1 at a Sequential Request bit in a Dataset Management field of the first write command.

A non-transitory computer-readable storage medium which stores a program for causing a computer of a recording apparatus, which records data to a memory card, to execute a recording method comprising:

• repeatedly transmitting 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;
• and
• when transmitting a first data recording instruction that designates a start portion of a first recording area as a recording destination, requesting 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.

• when transmitting a first write command that designates a start portion of a first recording area as a recording destination, requesting the memory card to execute data recording with the guaranteed minimum recording speed with respect to the first recording area by setting 1 at a Sequential Request bit in a Dataset Management field of the first write command.

A memory card that has a memory for data recording and that manages the memory for data recording as a plurality of recording areas and can execute data recording with a guaranteed minimum recording speed, comprising at least one processor and/or at least one circuit which functions as:

• a communication unit configured to perform communication with a host apparatus and receiving a data recording instruction that includes information designating recording target data and a recording destination;
• and
• a control unit configured to, in a case where a data recording instruction that includes a speed guarantee request and information that designates a start portion of a first recording area as a recording destination is received, perform control such that data recording with the guaranteed minimum recording speed is executed with respect to the first recording area.
