Abstract
Abstract A data reproducing method in which abrupt sound transitions as the end of a recorded tape is reached are eliminated. A predetermined time period corresponding to the length of the tape is inputted, and a time instant earlier by a predetermined period of time than the end of the time period at which the end of the tape is encountered is calculated. While plural pieces of music are being reproduced in a specified order for recording on the tape, a sum of the total time from the start of reproduction is iteratively calculated. When the sum reaches the calculated period of time, the total output level is gradually reduced to zero.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
152 words
A data reproducing method comprising the steps of: inputting in advance a predetermined input period of time; calculating a period of time which elapses from a start of said input period of time until a time instant earlier by a predetermined period of time than an end of said input period of time; reproducing a plurality of pieces of data recorded on a recording medium in a specified order; determining during the reproduction of each of said pieces of data a sum of periods of time of reproduction from the start of reproduction of said pieces of data; and when said sum of the periods of time of reproduction of said data reaches said period of time thus calculated, gradually decreasing an output level such that said output level is zero when said sum of the periods of time of reproduction of said data becomes equal to said input period of time.
Claim 2
Dependent Claim
152 words
A data reproducing method comprising the steps of: inputting in advance a predetermined input period of time; calculating a period of time which elapses from a start of said input period of time until a time instant earlier by a predetermined period of time than an end of said input period of time; reproducing a plurality of pieces of data recorded on a recording medium in a specified order; determining during the reproduction of each of said pieces of data a sum of periods of time of reproduction from the start of reproduction of said pieces of data; and when said sum of the periods of time of reproduction of said data reaches said period of time thus calculated, gradually decreasing an output level such that said output level is zero when said sum of the periods of time of reproduction of said data becomes equal to said input period of time.
Claim 3
Dependent Claim
23 words
The data reproducing method as claimed in claim 1, wherein said predetermined input period of time represents a playing time of a tape.
Claim 4
Dependent Claim
28 words
The data reproducing method as claimed in claim 1, wherein said time instant corresponds to a time shortly before the end of a playing time of a tape.
Claim 5
Dependent Claim
15 words
The data reproducing method of claim 1, wherein said pieces of data comprise music selections.
