<Skip playback> Skip playback has two modes, auto and manual. In either case, instructions are given at the leading edge of the on / off status signal generated by turning the rewind key or fast forward key on / off during playback of each mark period. When a jump is made to the start address of the mark period at the back or front of the mark period at the time when the mark period has been reached and the reproduction becomes possible (PRDY), the reproduction operation is started.
-Auto skip-
・ In auto skip playback mode, all mark periods are played back continuously.
-Manual skip-
・ In the manual skip playback mode, each mark period enters a paused state every time playback ends.

  FIG. 5 shows a flow at the time of recording a marking program resident in the main memory 120 executed by the CPU 110 of the system controller 100. For simplicity, an example in which only the physical address on the storage device is used for marking will be described. When the recording key 6 is first pressed to enter the recording mode pause state, the index i and the mark address matrix S (i, j) are cleared, and the physical properties of the storage device 400 that change with time according to the data rate. AD0, which is the start address of the recording area specified in the address function adx, which is a function block registered in the recording / reproducing program representing the address, is substituted. Next, when the determination button in the recording operation dialog is selected or the recording key 6 is pressed to enter the recordable state (RRDY), a loop for confirming whether the mark key has been pressed is entered. If it is confirmed that the mark key has been pressed, the minimum mark period is determined from the value of the address function adx in S (i, 1) representing the start address of the mark period of the mark address matrix S (i, j) (n x 3 matrix). A value obtained by subtracting Tm is substituted. When this is negative, AD0 is set. Thereafter, when the mark key is released, the value of the address function adx at the end address S (i, 2) of the mark period is set to the flag S (i, 3) indicating invalidity / validity of the secondary mark period. Substitute 1 Thereafter, this is repeated, and the secondary mark periods are arranged in the row direction in time order, and a mark address table is created in the main memory 120. When the recording operation is completed or interrupted and the recording mode is suspended, the value of i at that time becomes the mark address pair, that is, the number L of secondary mark periods. Thereafter, the magnitude relationship between S (i, 2) and S (i + 1,1) is examined. If S (i, 2) is large, the interval between adjacent mark periods is shorter than the minimum mark period Tm. Therefore, S (i, j) is invalidated as S (i, 3) = 0, and they are connected by integrating them into the upper mark period S (i + 1, j). As a result, the number of effective secondary mark periods becomes N, and a new mark address matrix T (i, j) created on the main memory 120 is saved in the nonvolatile memory 130 as a mark address table. To do.

  FIG. 6 shows a flow at the time of reproducing the marking program residing in the main memory 120 executed by the CPU 110 of the system controller 100. For simplicity, an example in which only the physical address on the storage device is used for marking will be described. When the reproduction key 2 is first pressed to enter the reproduction mode pause state, the mark address table associated with the reproduction data is downloaded from the nonvolatile memory 130 to a predetermined area in the main memory 120, and the index i is cleared. The start address AD0 of the reproduction area specified in the address function adx, which is a function block registered in the recording / reproduction program representing the physical address of the storage device that changes with time according to the data rate, is substituted. Next, when the decision button in the reproduction operation dialog is selected or the reproduction key 2 is pressed and the reproduction ready state (PRDY) is entered, it is tested whether the erasure button for erasing the mark in the mark period has been depressed. When the delete button is pressed, it tests whether the value of the address function is in the mark period. If so, the erasing instruction is validated and T (i, 3) is set to 0 to invalidate the mark period. After confirming the erase button, a loop for confirming whether the mark key 8 has been pressed during the reproduction operation is entered. The handling of the mark key 8 at this time is the same as in the recording mode, but the flag T (i, 3) for the new mark period is 2. Thereafter, this is repeated, and the secondary mark periods are arranged in the row direction in time order, and a mark address table is created in the main memory 120. When the reproduction operation is completed or interrupted and the reproduction mode is paused, the value of i at that time is the number of new mark address pairs, that is, the number M of secondary mark periods. Arranged in ascending order of T (i, 1) while removing invalid secondary mark periods from the mark address matrix T (i, j) that has been newly marked or erased and changed during the reproduction operation. Convert to replacement S (i, j). Thereafter, the magnitude relationship between S (i, 2) and S (i + 1,1) is examined. If S (i, 2) is large, the magnitude relationship between S (i, 3) and S (i + 1,3) is further increased. To test.
