Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solid-state recording / reproducing apparatus using a solid-state memory as a recording medium.

[0002]

2. Description of the Related Art Conventionally, a magnetic recording / reproducing apparatus such as a tape recorder using a magnetic tape as a recording medium has been used for recording / reproducing sound.

In addition to the recording / reproducing apparatus using such a magnetic tape, a solid-state recording / reproducing apparatus using a semiconductor memory such as a flash memory as a recording medium has been developed. Hereinafter, a memory using a semiconductor element is called a solid-state memory.

In the case of a conventional tape recording / reproducing apparatus, when the target tape position is significantly different from the current tape winding position, a fast-forward button (hereinafter,
The user has searched for a desired tape position by operating a rewind button (hereinafter referred to as FF button) or a rewind button (hereinafter referred to as REW button). At this time, a tape counter has also been used as a guide for finding the target position.

However, in a recording / reproducing apparatus using a recording medium such as a solid-state memory or a disk, unlike the case of a tape-shaped recording medium, it is possible to directly move to a target position. There is no concept of pressing the REW button for operation. In such a device, a chapter may be provided as a means for directly moving to a target position.

This is because, for example, in the case of music or the like, when a chapter is separated for each song and a chapter number is input, the chapter moves to the position of the head of the chapter. This is a system that is effective to some extent when there are many chapter divisions, but is completely ineffective when there are no chapter divisions at all.

That is, in this system, if there is only one chapter, it is not possible to search for the target position within that chapter. Therefore, if the recording time is long, the system moves to the target position. There is only a means to listen to the recorded sound as it is or to play it at a playback speed of n times.

If the reproduction speed is increased by n times, it is possible to move to the target position n times faster than the target position, but there is no reference for finding the target position, which is inconvenient. .

[0009]

As described above, in the conventional recording / reproducing apparatus using the solid-state memory, it was not possible to quickly move to the intended position intended by the user.

Therefore, in view of the above problems, the present invention is a solid-state recording / reproducing system capable of quickly accessing a target position intended by a user and performing recording / reproduction when recording or reproducing the solid-state memory. The purpose is to provide a device.

As a third example, apart from the method of advancing the display time count while the FF button 14 is being pressed, once the FF button 14 is pressed, the operation of advancing the count is continued until the stop button 13 is pressed. It is also possible to set the mode.

When the user confirms that the display counter advances to the desired display content and then presses the play button 11, the content of the displayed display counter, for example, on the memory 8 corresponding to the position of 30 minutes. By calculating the address and giving a command to the memory control means 9, predetermined data is loaded from the memory 8 and given to the DSP 6, and the contents from a predetermined 30 minutes are reproduced.

According to the above-described embodiment, when a solid memory is used to record a voice or the like for a long time and then the voice is reproduced, the target reproduction position can be quickly moved with the feeling of fast-forwarding and rewinding the conventional magnetic tape. It is possible to display the actual amount of time corresponding to recording or reproduction, and change the display of the actual amount of time in conjunction with the fast-forward or rewind operation to reach the target reproduction position while visually observing. Since the amount of time displayed on the display means corresponds to the read address on the solid-state memory, even when the fast-forward and rewind operations are performed a plurality of times or alternately, the fast-forward or rewind memory is used. The amount of time corresponding to the address above can always be displayed. Similarly, in addition to the fast forward and rewind operations, even when the recording, reproducing, and stopping operations are mixed, the amount of time corresponding to the address on the memory can always be displayed.
