Abstract
Abstract Continuous data is divided into a plurality of portions and then recorded on a recording medium such as a magnetic tape or the like so that, even when a recording medium is exchanged, the divided data thus recorded can be continuously reproduced. During a period in which a recording head is moved to a second recording position after the recording at a first recording position is ended, corresponding data reproduced from a recording medium even when the recording medium is exchanged is written in a memory means in which an input signal applied to an input terminal is written.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
224 words
A digital data reproducing apparatus for reproducing continuous digital data from a recording medium on which said continuous digital data is divided into at least first and second portions which are respectively recorded at first and second locations of said recording medium which are spaced apart from each other, said digital data reproducing apparatus comprising: (a) searching means for searching a beginning part of at least said second portion when said recording medium is installed in said reproducing apparatus and for generating a detected output when the beginning part is found; (b) memory means for storing the digital data; (c) memory control means for controlling said memory means such that the beginning part of at least said second portion is written in said memory means when said detected output is generated; (d) reproducing means for reproducing said first portion of said continuous digital data by a reproducing head; (e) moving means for moving said reproducing head and said recording medium relative to each other so that said reproducing head relatively moves from said first location to said second location; and (f) means for reading out the beginning part of said second portion from said memory means while said reproducing head relatively moves from said first location to said second location, whereby said first and second portions of said continuous digital data are reproduced continuously.
Claim 2
Dependent Claim
224 words
A digital data reproducing apparatus for reproducing continuous digital data from a recording medium on which said continuous digital data is divided into at least first and second portions which are respectively recorded at first and second locations of said recording medium which are spaced apart from each other, said digital data reproducing apparatus comprising: (a) searching means for searching a beginning part of at least said second portion when said recording medium is installed in said reproducing apparatus and for generating a detected output when the beginning part is found; (b) memory means for storing the digital data; (c) memory control means for controlling said memory means such that the beginning part of at least said second portion is written in said memory means when said detected output is generated; (d) reproducing means for reproducing said first portion of said continuous digital data by a reproducing head; (e) moving means for moving said reproducing head and said recording medium relative to each other so that said reproducing head relatively moves from said first location to said second location; and (f) means for reading out the beginning part of said second portion from said memory means while said reproducing head relatively moves from said first location to said second location, whereby said first and second portions of said continuous digital data are reproduced continuously.
Claim 3
Dependent Claim
25 words
A digital data reproducing apparatus according to claim 1, wherein said digital data is a digital audio signal and said recording medium is a tape.
Claim 4
Dependent Claim
32 words
A digital data reproducing apparatus according to claim 1, wherein said memory control means includes encoding means for encoding the digital data to be written in said memory means to compressed data.
Claim 5
Dependent Claim
25 words
A digital data reproducing apparatus according to claim 3, wherein said reading means includes decoding means for decoding the compressed data into the original data.
Claim 6
Dependent Claim
35 words
A digital data reproducing apparatus according to claim 1, further comprising control memory means for storing address data indicating the location at which said first and second portions of said continuous digital data are recorded.
Claim 7
Dependent Claim
178 words
A digital data reproducing apparatus for reproducing continuous digital data from a recording medium on which said continuous digital data is divided into at least first and second portions which are respectively recorded at first and second locations of said recording medium which are spaced apart from each other, said digital data reproducing apparatus comprising: searching means for searching a part of at least one of said first and second portions when said recording medium is installed in said reproducing apparatus; memory means for storing said part searched by said searching means; reproducing means for reproducing said first portion of said continuous digital data by a reproducing head; moving means for moving said reproducing head and said recording medium relative to each other so that said reproducing head relatively moves from said first location to said second location; and means for reading out said part stored in said memory means while said reproducing head relatively moves from said first location to said second location, whereby said first and second portions of said continuous digital data are reproduced continuously.
Claim 8
Dependent Claim
178 words
A digital data reproducing apparatus for reproducing continuous digital data from a recording medium on which said continuous digital data is divided into at least first and second portions which are respectively recorded at first and second locations of said recording medium which are spaced apart from each other, said digital data reproducing apparatus comprising: searching means for searching a part of at least one of said first and second portions when said recording medium is installed in said reproducing apparatus; memory means for storing said part searched by said searching means; reproducing means for reproducing said first portion of said continuous digital data by a reproducing head; moving means for moving said reproducing head and said recording medium relative to each other so that said reproducing head relatively moves from said first location to said second location; and means for reading out said part stored in said memory means while said reproducing head relatively moves from said first location to said second location, whereby said first and second portions of said continuous digital data are reproduced continuously.
Claim 9
Dependent Claim
