Abstract
Abstract An audio disc reproducing apparatus, which includes a controller for controlling a head and a memory and which receives an operator inputted operation information from an input device. The controller controls the memory to retain data read from the disc when data reproducing is stopped by a halt request made via the input device in the course of the data reproducing, and if the controller receives a request for resumption of the data reproducing from the input device, the controller controls the memory to start reading out the retained data in the memory.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
174 words
An audio reproducing apparatus comprising: readout means for reading out data from a recording medium at a first data transfer rate; storing means for storing the data outputted from the readout means; signal processing means for reading out data from the storing means at a second data transfer rate, processing the data read out from the storing means and outputting the processed data as a reproduced audio signal; input means for inputting operation information entered by the user; and control means responsive to a halt request from the input means for controlling the storing means and the readout means and directing the storing means to retain the data in the storing means thereafter when data outputting is stopped by the halt request made, and if the control means receives a request for resumption of data reproducing from the input means within a predetermined period of time, the control means controls the storing means to resume reading out the retained data in the storing means and outputting the processed data as a reproduced audio signal.
Claim 2
Dependent Claim
174 words
An audio reproducing apparatus comprising: readout means for reading out data from a recording medium at a first data transfer rate; storing means for storing the data outputted from the readout means; signal processing means for reading out data from the storing means at a second data transfer rate, processing the data read out from the storing means and outputting the processed data as a reproduced audio signal; input means for inputting operation information entered by the user; and control means responsive to a halt request from the input means for controlling the storing means and the readout means and directing the storing means to retain the data in the storing means thereafter when data outputting is stopped by the halt request made, and if the control means receives a request for resumption of data reproducing from the input means within a predetermined period of time, the control means controls the storing means to resume reading out the retained data in the storing means and outputting the processed data as a reproduced audio signal.
Claim 3
Dependent Claim
56 words
An audio reproducing apparatus according to claim 1, wherein the recording medium is a disc and the apparatus further comprises servo means for controlling the readout means, the servo means being controlled by the control means to complete a build-up operation before the retained data in the storing means is depleted upon resuming the data reproducing.
Claim 4
Dependent Claim
41 words
An audio reproducing apparatus according to claim 1, wherein the control means comprises timer means, the timer means counts a predetermined time from the time when the data reproducing is stopped in response to the halt request from the input means.
Claim 5
Dependent Claim
53 words
An audio reproducing apparatus according to claim 3, wherein the control means comprises reset means which generates a reset signal when the predetermined time as timed by the timer means is passed, the reset signal from the reset means is supplied to the storing means to clear the storing means of stored data.
Claim 6
Dependent Claim
33 words
An audio reproducing apparatus according to claim 1, wherein the reproducing apparatus comprises a transducer head as the readout means and a driving apparatus which drives the recording medium relative to the head.
Claim 7
Dependent Claim
22 words
An audio reproducing apparatus according to claim 1, wherein the first data transfer rate is faster than the second data transfer rate.
