Abstract

Abstract An information memory system suitable for a recording medium such as an optical card which reciprocates. This memory system includes: a reading apparatus for reciprocating the recording medium and reading out the information recorded on the recording medium; an auxiliary memory apparatus different from the recording medium; and a managing apparatus for managing the reading apparatus and the auxiliary memory apparatus. The reading apparatus transfers the information read out of the recording medium to the managing apparatus, and the managing apparatus stores the information transferred from the reading apparatus to the auxiliary memory apparatus while new information is being read out. The reading apparatus has a memory for temporarily storing the information read out of the recording medium and transfers the information from the memory to the managing apparatus when the recording medium is reversed. With this system, the readout information can be efficiently transferred to the host computer side and can be processed. Therefore, the idle time of the host side can be extremely effectively used.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 121 words
An information memory system comprising: moving means for reciprocating a recording medium; reading means for reading out information recorded in the recording medium, during motion of the recording medium; a buffer memory, for temporarily storing the information read out by said reading means; storing means, different from the recording medium, for storing information therein; a host computer for supervising said storing means and said reading means; and transfer means for transferring the information stored in said buffer memory to said host computer when the direction of movement of the recording medium is reversed, wherein said host computer causes the information transferred by said transfer means to be stored in said storing means while said reading means in reading out new information.
Claim 2
Dependent Claim 121 words
An information memory system comprising: moving means for reciprocating a recording medium; reading means for reading out information recorded in the recording medium, during motion of the recording medium; a buffer memory, for temporarily storing the information read out by said reading means; storing means, different from the recording medium, for storing information therein; a host computer for supervising said storing means and said reading means; and transfer means for transferring the information stored in said buffer memory to said host computer when the direction of movement of the recording medium is reversed, wherein said host computer causes the information transferred by said transfer means to be stored in said storing means while said reading means in reading out new information.
Claim 3
Dependent Claim 24 words
An information memory system according to claim 1, wherein said transfer means transfers the information while the recording medium is being accelerated or decelerated.
Claim 4
Dependent Claim 17 words
An information memory system according to claim 1, wherein said storing means comprises a magnetic hard disk.
Claim 5
Dependent Claim 17 words
An information memory system according to claim 1, wherein said recording medium is a card-shaped recording medium.
Claim 6
Dependent Claim 39 words
An information memory system according to claim 1, wherein said host computer includes a memory for storing the the information transferred by said transfer means, and wherein the information stored in said memory is stored in said buffer memory.
Claim 7
Dependent Claim 21 words
An information memory system according to claim 1, further comprising retrieving means for retrieving desired information stored in said storing means.
Claim 8
Dependent Claim 21 words
An information memory system according to claim 6, further comprising display means for displaying the information retrieved by said retrieving means.
Claim 9
Dependent Claim 46 words
An information memory system according to claim 6, wherein said retrieving means includes input means for inputting retrieving information for retrieving desired information, and wherein the retrieval operation is prohibited when the retrieving information inputted by said input means is not associated with the recording medium.
