Abstract

Data 30 is recorded into storages 0 to 3 in parallel. Writing sectors are selected from a plurality of clusters so that the sectors are continuously arranged in each cluster, and the data is simultaneously written into the selected sectors. In the case where the sectors numbered in the original order are written into the storages 0 to 3 in parallel, the data of No. 0 is recorded into the head sector in the cluster of the storage 0, the data of No. 16 is recorded into the head sector in the cluster of the storage 1, the data of No. 32 is recorded into the head sector in the cluster of the storage 2, and the data of No. 48 is recorded into the head sector in the cluster of the storage 3, respectively. Thus, the data is arranged in the original order into the cluster constructed in the same storage. When the data is written into a plurality of storages in parallel, the compatibility of the file format of the written data is held.

Claims

1. A recording system having a detachable memory apparatus with a non-volatile memory formed of a plurality of clusters each having a plurality of sectors, and a data recording apparatus for recording data constructed by a plurality of continuous sectors into said memory apparatus, comprising:

address designating means for designating an address of the sector for recording the data; and

recording means for recording the data into the sector designated by said address designating means,

wherein said address designating means designates a plurality of sector addresses and designates the addresses so that said continuous sectors of said recording data are recorded as continuous sectors in said cluster, and

said recording means simultaneously records the data into said plurality of sectors.

2. A data recording apparatus using a detachable memory apparatus including a non-volatile memory as a recording medium, comprising;

an address designator for recording data in a plurality of sectors into said memory apparatus in parallel,

wherein said address designator designates a plurality of sector addresses and designates the addresses so that continuous sectors of said recording data are recorded as sectors which are continuous in a cluster.

3. A memory apparatus which is detachable to/from a data recording apparatus, comprising:

a non-volatile memory;

recording means for recording data; and

interface means arranged between said data recording apparatus and said non-volatile memory,

wherein said recording means simultaneously records the data into a plurality of sectors so that continuous sectors of said recording data are recorded as sectors which are continuous in a cluster.

4. A memory apparatus according to claim 3, further comprising address designating means for designating an address in which said recording means records the data.

5. A memory apparatus according to claim 3, wherein a plurality of data having offsets of the number which is equal to the number of sectors of the cluster is converted into parallel data and said parallel data is simultaneously written into a plurality of storages.
